A rectangle has two right angles. In a rectangle, opposite sides are equal in length and all interior angles are 90 degrees. This geometric property distinguishes a rectangle from other shapes, such as squares or parallelograms, which may also have right angles but do not necessarily have exactly two right angles.

The simplest shape that can have 2 right angles is a rectangle or a square. You can make an unlimited number of more complex shapes, though. A house shape is a pentagon with 2 right angles--you could even make it with 3 right angles.
A shape with 5 angles has 5 sides, always. Pentagons have 5 sides, and 5 angles.
You can find out how many angles are in a shape by counting how many edges a shape has. for instance.. a square has 4 edges so it has 4 angles
The sum of the angles in the 33 sided shape is 5,580 degrees
A shape with 5 sides and 5 angles is a pentagon.
A Nonagon has 9 angles, and 9 sides.
