360⁰
The three transformation in angles are translation , rotation , reflection .
1 complete rotation = 360o 1 right angle = 90o 360o ÷ 90o = 4 There are 4 right angles in 1 complete rotation.

A full rotation = 360°; a right angle = 90° → there are 360° ÷ 90° = 4 right angles in a full turn.
Right angles are ninety degree angles. That is equal to one quarter of a complete rotation.

Angles do not have lengths. They are measured in terms of rotation about the vertex.
They do not alter the size nor the angles of the shape.
