Look at the figure drawn below and answer the questions at the side of the figure. Place figure here 1. Name the center of this circle. 2. Name one radius of this circle. 3. Name a diameter of this circle. 4. What is the distance around a circle called? 5. Name three objects around you that have a circular shape. What are you looking for? What do you need to answer the questions? Estimate what your answer(s) might be ( think of both numbers and terms to be used)? Write out the methods that you will use to solve the problem and show your work in calculating the answer(s). Your answer(s) are (make sure you are close to your estimate and the units are correct): 2. Work through the following questions about measuring line segments. 1. What is the length of a line segement that extends along the edge of this page, from top to bottom, in inches? 2. What is this length in centimeters? 3. What is the length (in inches) of the line segement that joins the opposite corners of this page? Is this line segement a diagonal of the page? How many diagonals are there? Are they equal in length? 4. If you fold this paper- from top to bottom - in thirds, what is the smallest size enveloppe the folded page will fit into? 5. Draw a line segement 2 3/4 inches long. 6. Name some ways you can measure the length of the room you are in now. 7. Name some ways to get an approximate measure for the length of a parcel of land. think of ways other than measuring it with a tape measure. What are you looking for? What do you need to answer the questions? Estimate what your answer(s) might be ( think of both numbers and terms to be used)? Write out the methods that you will use to solve the problem and show your work in calculating the answer(s). Your answer(s) are (make sure you are close to your estimate and the units are correct): 3. On your paper, write down how many degrees are in each of the following angles - as indicated on the protractors shown: Place figure here 2. With your protractor, measure each of the angles shown below. Write the angle measure on your paper. Place figure here 4. Now, on your own paper, follow the procedure outlined in example 2 ( in your book page 15) and draw angles with these measurements: 1. 30o 2. 45o 3. 60o 4. 90o 5. 135 o What are you looking for? What do you need to answer the questions? Estimate what your answer(s) might be ( think of both numbers and terms to be used)? Write out the methods that you will use to solve the problem and show your work in calculating the answer(s). Your answer(s) are (make sure you are close to your estimate and the units are correct): 5. 1.Draw a right angle on your paper by tracing the right angle of one of your drawing tools. 2. Use your 45-45-90 drawing triangle to draw a line that bisects the right angle you just drew. ( bisect means to divide in half) 3. Draw another right angle on your paper. then use your 30-60-90 drawing triangle to divide the right angle into three equal parts. 4. Use your Accu-Line drawing kit to draw angles of 90o, 60o, 45o and 30o. What are you looking for? What do you need to answer the questions? Estimate what your answer(s) might be ( think of both numbers and terms to be used)? Write out the methods that you will use to solve the problem and show your work in calculating the answer(s). Your answer(s) are (make sure you are close to your estimate and the units are correct): 6. 1. Name three places in the room where you see perpindicular lines. 2. Use the drawing below to answer the questions that follow. Place drawing here a. If Angle 1 = 90o, what can you say about lines L and M? b. If line P is perpindicular to line L what is the measure of Angle 2? c. If Angle 1= 90o, can you say what the measure of Angle 3 is? d. If Angle 1 = 90o, what can yousay about the measure of Angle 4? e. What statement can you make about lines M and P? 7. 1. Choose a place on your paper where you have several inches of clear space in all directions and draw a line segment 1 1/2 in ches long. label one endpoint A and the other endpoint B. 2. Use any method you wish to draw a perpindicular line at point A on the line segment you just drew. Extend the perpindicular line 2 inches on one side of segment AB. Erase any part of the perpindicular line that is on the opposite side of the segment AB. Label the endpoint C. Draw another 2 inch perpindicular segment at point B, making sure you draw it on the same side of segment AB as the first perpindicular segment. Name the endpoint of this segment D. 3. Connect points C and D. 4. Measuring with your ruler, mark the middle of each of the 2 inch sides and connect those two points with a line segment. 5. If you did not use an Accu-Line drawing kit to complete Steps 1-4, do so now. 6. Look at the shape you have drawn. List three physical objects that the shape might represent. What are you looking for? What do you need to answer the questions? Estimate what your answer(s) might be ( think of both numbers and terms to be used)? Write out the methods that you will use to solve the problem and show your work in calculating the answer(s). Your answer(s) are (make sure you are close to your estimate and the units are correct): 8. Lets try drawing a different set of parallel lines. On a seperate sheet of paper, draw a horizontal line with the help of a T square. Place one of your drawing triangles so that its longeest side lies along the line you just drew. Then draw along one of the other sides of the drawing triangle. Place figure here Next, slide the triangle along the base line to a new position - using the edge of the T square to help you. Then draw a line along the same side of the triangle you did the first time. Repeat the process several times. Label the lines and number the angles formed by the lines, as shown in the next drawing. Place figure here What are you looking for? What do you need to answer the questions? Estimate what your answer(s) might be ( think of both numbers and terms to be used)? Write out the methods that you will use to solve the problem and show your work in calculating the answer(s). Your answer(s) are (make sure you are close to your estimate and the units are correct): 9. 1. Which tools in Figure 6-10 have a right angle as part of the tool? 2. Why do you think a right angle is so important to a carpenter? 3. What do you think you do with a try square? The name gives you a cluse.  4. A T bevel consists of two flat pieces of metal held together with a wing nut. If you loosen the wing nut, you can move the sides farther apart or close together. Then , when you tighten the wing nut, the sides keep the shape you set. What could you measure with this tool? Place Figure 6-10 here What are you looking for? What do you need to answer the questions? Estimate what your answer(s) might be ( think of both numbers and terms to be used)? Write out the methods that you will use to solve the problem and show your work in calculating the answer(s).
