Front

What is the area of a shape?

Back

The space inside an object, measured in square units.

Front

What is the perimeter of a shape?

Back

The total distance around the outside of a shape.

Front

How do you calculate the area of a rectangle?

Back

Multiply the length by the width (Area = length × width).

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width).

Front

What does it mean for two shapes to be congruent?

Back

They are the same size and shape.

Front

What does it mean for two shapes to be similar?

Back

They have the same shape but may be different sizes.

Front

If a square has a side length of 4 cm, what is its area?

Back

16 square cm (Area = side × side).

Front

If a rectangle has a length of 5 cm and a width of 3 cm, what is its perimeter?

Back

16 cm (Perimeter = 2 × (5 + 3)).

Front

What is symmetry in shapes?

Back

When one half of a shape is a mirror image of the other half.

Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.
