Right Angles

A right angle is an internal angle equal to 90°

This is a right angle

See that special box symbol in the corner? That says it is a right angle. The 90° is rarely written in. If we see the box in the corner, we are being told it is a right angle.

Plenty of right angles!

All the angles below are right angles:

Three right angles rotated in different directions, each containing a square symbol

A right angle can be in any orientation or rotation as long as the internal angle is 90°

Never argue with a 90° angle, it is always right!

Try it yourself: Look around the room right now. How many right angles can you find?
