My 2D geometry word wall word: Season 1, Post 1: Perpendicular.

For every math unit, Ms Porcari has given us a "word wall word". She gives the class their own word  to describe, get an image, and a QR code. My word was perpendicular. Being perpendicular  is when two lines cross each other and form a right angle or a 90 degree angle. 
For example: if I have line A and line B and they cross and make a right angle, that is called being perpendicular.
