Question

Match the vocabulary word with the correct definition. 1. angle lines that intersect to form right angles. 2. acute angle the union of two rays that have a common endpoint. 3. right angle an angle with a measure greater than 90° but less than 180°. 4. obtuse angle an angle whose measure is greater than zero and less than 90°. 5. bisector of an angle a set of points which divides the angle into two angles of equal measure. 6. perpendicular lines an angle whose measure equals 90°.

Answer 1

1. Angle: the union of two rays that have a common endpoint. 
2. Acute Angle: an angle whose measure is greater than zero and less than 90°
3. Right Angle: an angle whose measure equals 90°.
4. Obtuse Angle: an angle with a measure greater than 90° but less than 180°.
5. Bisector of an Angle: a set of points which divides the angle into two angles of equal measure.
6. Perpendicular Line: lines that intersect to form right angles.
