Pentagon.
Regular shapes:all sides and angles are the same Irregular shapes: different angle and sides
No, right triangles do not.

An angle must have 2 sides or it is no longer an angle.
Angle
Regular shapes:all sides and angles are the same Irregular shapes: different angle and sides
It is a point where two sides of the shape meet.

No, right triangles do not.
Shapes that always contain perpendicular sides include rectangles and squares. In these shapes, adjacent sides meet at right angles (90 degrees). Additionally, right triangles also have one angle that is a right angle, resulting in two sides being perpendicular to each other.
