two straight angles
Chat with our AI personalities
By a straight angle I assume you mean an 180° angle, so two angles that form a 180° angle would be called supplementary angles.
Complementary
Right angles aren't formed by other angles - it is already an angle itself. However, if you bisect a right angle, it becomes two acute angles.
if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
Perpendicular.
