What are two adjacent angles whose measures are always supplementary?
Two right angles would always be supplementary because the sum of their angles is 180 degrees.
Are two adjacent angles whose exterior sides are opposite rays always complementary?
No? Wouldn't they then be supplementary? Opposite rays make a straight angle/line, and if the exterior sides made the straight angle, the adjacent angles would be supplementary. ...Right?
Are adjacent right angles are always complementary?
No, but they're "supplementary".Two "complementary" angles add up to 90°. Each right angle is 90° all by itself,so two of them aren't complementary.But two "supplementary" angles add up to 180°, and that certainly describestwo right angles of 90° each.
Are vertical and supplementary right angles?
No, right angles are 90 degrees, supplementary and vertical angles are 180 degrees.
Angles that are congruent and supplementary must be?
Angles that are congruent and supplementary must be right angles.
