complementary angles
If you're talking about two angles adding up to equal a total measure of 90, then the answer to your question is complementary angles.
Two right angles (90 degrees each) equal 180 degrees (a straight angle).
Two angles whose measures add to 90 are complementary angles. An example is 45 and 45.
The sum of two complementary angles is 90°.If the ratio is 2:3 then there are 5 parts in total.90 ÷ 5 = 18.The angles measure 2 x 18 = 36° and 3 x 18 = 54°.

Yes. A triangle has 180 degrees total, so if one of them is a right angle, which means it is 90 degrees, the sum of the remaining two angles is 180-90=90 degrees.
Two angles with a sum of 90 are called complimentary angles.
