Squares and rectangles always have, but anyshape
with more than 3 sides can have 2 right angles.
A restangle can be it but it has 4 angles at 90 degrees.
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.
A restangle can be it but it has 4 angles at 90 degrees.

It is impossible for a triangle to have 2 angles of 90 degrees
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
Any closed shape can have angles greater than 90 degrees. A triangle doesn't need to have any, but it can have one of them if it wants to. A shape with four sides doesn't need to have any, but it can have 2 or 3 of them if it wants to. Shapes with more than 4 sides must have some.
