Today's Objective

Today we will be talking about different types of shapes, learning about edges and vertices, making new shapes from old shapes and learning about faces on 3 dimensional shapes.

Lets Learn About Shapes!

Lets take a look at two – dimensional figures.

• Square

• Circle

•Ellipse

•Triangle

•Rectangle

• Rhombus

•Trapezoid

•Parallelogram
