1
Q
Congruent angles
A
Congruent angles are angles that have the same angle measure.
alpha = 90 beta = 90
alpha and beta congruent
2
Q
Complementary angels
A
Two angles are considered complementary if the sum of their angle measures is exactly 90 degrees.
If one angle measures 30 degrees, the angle complementary to it would measure 60 degrees (since 30 + 60 = 90).
3
Q
Supplementary angles
A
Two angles are considered supplementary if the sum of their angle measures is exactly 180 degrees
if one angle measures 110 degrees, the angle supplementary to it would measure 70 degrees (since 110 + 70 = 180).
