2D Shapes

​I can recognize 2D shapes and their attributes.

Examples? What do you see they have in common?

Agenda

• Introduce the 2D shapes

• Collaborate board

• Exit Ticket

Attributes of 2D Shapes

• Angles

• Vertices

• Sides

An angle is space inside a 2D shape where two sides meet.

A vertices (corner) is where two sides connect.

A side is a straight line on a 2D shape
