If two angles of a triangle are complementary, it means they add up to 90 degrees. Since the sum of the angles in a triangle is always 180 degrees, the third angle would be 180 degrees minus 90 degrees, which equals 90 degrees. Therefore, the measure of the third angle in this triangle would be 90 degrees.

What if two angles of a triangle are complemenatr what is the measure of the third angle?

The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.

What possible measures for angle a and angle b with triangle abc is a right triangle with the right angle at c?

'a' and 'b' must both be acute, complementary angles.


Are the two acute angles in a right triangle supplementary?

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.
