Two angles that are equal to 90 degrees are Complimentary.
complementary angles.
They are complementary angles
The 4 equal angles of 90 degrees within a square add up to 360 degrees
A rectangle.
Two angles that are equal to 90 degrees are Complimentary.
One right angle is equal to 90 degrees, or a vertical line extending from the o degree plane. Therefore, two right angles, presumably side to side, would have 180 degrees, since together the would be supplementary angles. Supplementary angles are two angles which combine to from 180 degrees, and 90 plus 90 would equal 180 degrees. Look at angle DBE and at angle EBC. Each are 90 degree angles, or right angles, and together equal 180 degrees.
If all 4 sides are equal and the angles are not 90 degrees it is a rhombus.
Acute angles (less than 90 degrees) Obtuse angles (greater than 90 degrees) Right angles ( equal to 90 degrees)
If you mean "Does the sum of two angles equal exactly 90 degrees?" it is yes.
complementary angles.
complementary angles
Supplementary means the sum of two angles equal to 180 degrees. The Sum of 90 degrees would be complimentary, where the sum of two angles equal to 90 degrees.
No because they equal 180 degrees
Supplementary angles are two angles that add up to 180 degrees. They are only equal if they both equal 90 degrees.
Yes opposite angles are equal but not at 90 degrees.
