Complementary angles add up to ninety degrees. Triangles must hold 180.
Taking these facts together, think of this: you have two angles in a triangle where they add up to ninety. This means that the other angle in the triangle must hold the other ninety.
I'm not going to answer your question, but I'll pose you the question you should have asked: What is a triangle called when it has one angle that is exactly ninety degrees?

Can two angles of a right triangle be complementary?
The two angles, other than the right angle itself, MUST be complementary.
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 is form when two complementary angles share one ray?
The complementary angles form a right angle with the shared ray.
Which term describes two adjacent angles that form a right angle?
Complimentary angles
Can one of two complementary angles be obtuse?
No, one of two complementary angles cannot be obtuse, because only two acute angles that add up to 90 degrees are complementary and that an obtuse angle on its own is greater than 90 degrees.
Can an obtuse triangle have two complementary interior angles?
No. A triangle with two complementary interior angles will always result into right triangle. The sum of the complementary angles will always be 90 degrees and the other one will be 90 too.
Can two angles of a right triangle be complementary?
The two angles, other than the right angle itself, MUST be complementary.
What property of two acute angles of a right triangle have?
They are complementary.
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.
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.
If two angles of a triangle are complementary what is the measure of the third angle?
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 is form when two complementary angles share one ray?
The complementary angles form a right angle with the shared ray.
What do you call two supplementary angles?
a complementary angle
What are some examples of complementary angles?
ANY two angles that total 90o, eg the "other" angles in a right-angled triangle.
What do you call two angles which add to 90 degree?
They are complementary
If two angles of a triangle are complementary find the number of degrees in the third angle?
90
What do you call a triangle that had two or more angles?
Every triangle has at least three angles.
