Right Angles

Right Angles

1. If an angles measure is 90 degrees, then it is a right angle

   • If two angles sum is equal to 90 degrees, then they're complementary

2. If a diagram is given, then you can't assume that the angle is a right angle

3. If two angles are right angles, then they're congruent

4. If lines, rays and segments are perpendicular, then they form right angles.

5. If two angles sums are 90 degrees, then they're complementary angles

6. If an angle's measure is 90 degrees, then it's a right angle

7. If a diagram is given, then do not assume that the angle is a right angle

8. If two angles are right angles, then the angles are congruent

9. If lines, rays, or segments are perpendicular, then they are right angles
