This unit focuses on _______________ and _______________. 2. A point identifies a _______________ - or _______________ - in space. 3. This is a _______________. P C 4. The line in question number 3 is named line _____ _____ or line _____ _____. 5. The part of a line that has a beginning poing and an ending point is a _______________ _______________. 6. Draw a line segment. Name the line segment LM. 7. The drawing below is an _______________. A B C 8. Sides BA and BC are called _______________. A _______________ is a part of a line with only one endpoint. 9. When naming rays, start with the name of the _______________ or the end without the arrow. In question 7 the endpoint is labeled _____. 10. The point where rays BA and BC meet is called the _______________. The vertex in question 7 is labeled _____. 11. By naming the _______________ of the angle you can name the angle. The angle in question 7 is named: angle _____ _____ _____, or angle _____ _____ _____. 12. Label the angle in question 7; angle number 4. 12. The point naming the vertex is always the _______________ letter of the angles name. 13. A _______________ is formed by joining all the points that are a given distance from a central point. 14. This central point is called the _______________ of the circle. 15. A segment from the center of the circle to a point on the circle is a _______________ of the circle. All radii of the same circle have the same _______________. 16. A straight segment drawn from one side of the circle, THROUGH THE CENTER, to the other side is the _______________ of the circle. 17. The diameter of a circle is _______________ the length of a radius of that circle. 18. The distance all the way around a circle is the _______________ of the circle. 19. Identify the following parts of this circle. D RADIUS __________ DIAMETER __________ C B CENTER __________ Circumference is the ______________________________ 20. The length of a line segment is the _______________ between its end points. 21. When writing the measure of anything, be sure to include the _______________ of that measurement. 22. Angles are measured as part of a _______________. 23. The circle is divided into 360 parts or _______________. 24. A full circle is __________o. A half circle is __________o. This is called a _______________ angle. A fourth of a circle is __________o. This called a _______________ angle. 25. A _______________ is a tool for measuring the degrees in an angle. 26. To use a protractor, first align one side of an _______________ with the straight line on the protractor. Move the protractor so that the midpoint dot on the protractor is over the _______________ of the circle. Observe where the second side of the angle corsses the protractor and read the measure listed there. 27. When using a protractor, you measure an angle that is 30o, this angle is also labeled as 150o, WHY? TO DRAW AN ANGLE 28. First draw a line _______________. 29. Mark a point on this line for the _______________. Place the protractor over this line segment and vertex. Make a small mark at the desired angle on the protractor. 30. Remove the protractor and make a line from the _______________ to the dot. 31. Common angles can be drawn by using drawing triangles and simply tracing the desired angle. Triangles include the following angles; _____, _____, _____ and _____. 32. If two lines meet to form a right angle (90o), the two lines are _______________. 33. If two lines are on the same flat surface and do not cross, no matter how far they are extended, the two lines are called _______________. 34. Two lines that are _______________ to the same line are _______________ to each other. 35. Two lines that meet another line so that the _______________ angles have the same _______________ are _______________ to each other.
