supplementaryA:Two angles whose sum measures a right angle are complementary angles.
No, they are complementary angles. Supplementary angles sum to 180o Complementary angles sum to 90o. The three angles of a triangle sum to 180o. If one is 90o (the right angle), then the other two sum to 180o - 90o = 90o and so are complementary.
Yes, the definition of complementary angles is that their sum is 90 degrees. All 90 degree angles are by definition right angles.
A right angle triangle has a 90 degree angle and two acute angles and the 3 angles add up to 180 degrees
The sum of the 3 angles of a triangle will ALWAYS equal 180 degrees.
