Lesson 2 Properties of Rectangles and Squares

Front

What is a rectangle?

Back

A rectangle is a quadrilateral with opposite sides that are equal in length and four right angles (90 degrees).

Front

What is a square?

Back

A square is a special type of rectangle where all four sides are equal in length and all angles are right angles (90 degrees).

Front

What are the properties of rectangles?

Back

1. Opposite sides are equal in length. 2. All angles are right angles. 3. Diagonals bisect each other and are equal in length.

Front

What are the properties of squares?

Back

1. All sides are equal in length. 2. All angles are right angles. 3. Diagonals bisect each other, are equal in length, and are perpendicular.

Front

What is the relationship between consecutive angles in a parallelogram?

Back

Consecutive angles in a parallelogram are supplementary, meaning they add up to 180 degrees.

Front

If the length of a rectangle is 10 cm and the width is 5 cm, what is the perimeter?

Back

Perimeter = 2(length + width) = 2(10 + 5) = 30 cm.

Front

If the area of a rectangle is 50 cm² and the width is 5 cm, what is the length?

Back

Area = length × width; therefore, length = Area / width = 50 / 5 = 10 cm.

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the area of a square?

Back

Area = side × side (or side²).

Front

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

Back

Area = 4 cm × 4 cm = 16 cm².
