What is a polygon?

• A closed figure with two straight sides.

• A closed figure with three or more straight sides.

• A type of circle with straight edges.

• An open figure with curved sides.

How do you find the area of a triangle?

• Area = base × height

• Area = 1/2 × base × height

• Area = base + height

• Area = base × height ÷ 2

What is the relationship between area and perimeter?

• Area measures the distance around a shape; perimeter measures the space inside it.

• Area measures the space inside a shape; perimeter measures the distance around it.

• Area and perimeter are the same; they both measure the size of a shape.

• Area measures the volume of a shape; perimeter measures the surface area.
