Squares and rectangles always have, but anyshapewith more than 3 sides can have 2 right angles.
complementary angle
It is a 4 sided quadrilateral shape having 2 pairs of parallel sides and 4 interior angles of 90 degrees as well as 2 diagonals
complementary angles..there are a lot any 2 angles when added together that make 90 degreesComplementary
an isocelesANS2:Any triangle that has one right angle will have 2 acute angles. An acute angle is less than 90 degrees and the sum of all angles in a triangle is 180 degrees. The sum of the other two angles would have to add to 90 degrees so they would both have to be less than 90 degrees.

Rhombus
It is impossible for a triangle to have 2 angles of 90 degrees
complementary angles
There cannot be such a shape because a triangle is a 2-D shape and the sum of its internal angles in 180 degrees. However, it is possible to have a triangular shape which has three right angles on convex surfaces.
Complimentary Angles
a square. all of the angles are 90 degrees or pi/2 radians.
They are called complimentary angles.
Complementary angles
complementary angles
Complementary angles are angles that add up to 90 degrees. So, if 88 + x = 90, then x (the complement) must equal 2 degrees. (88 + 2 = 90 degrees)
