12/9/24: Part 1: Properties of all 4 types of parallelograms

Front

What are the properties of a rectangle?

Back

1. Opposite sides are equal and parallel. 2. All angles are right angles (90 degrees). 3. Diagonals bisect each other and are equal in length.

Front

In a parallelogram, what can be said about the diagonals?

Back

The diagonals of a parallelogram bisect each other.

Front

What is the definition of a parallelogram?

Back

A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length.

Front

If m∠A and m∠B are consecutive angles in a parallelogram, what is their relationship?

Back

Consecutive angles in a parallelogram are supplementary, meaning m∠A + m∠B = 180 degrees.

Front

What is the property of opposite angles in a parallelogram?

Back

Opposite angles in a parallelogram are equal.

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

If the lengths of the sides of a rectangle are 5 cm and 10 cm, what is the area?

Back

Area = 5 cm × 10 cm = 50 cm².

Front

What is the relationship between the sides of a rhombus?

Back

In a rhombus, all four sides are of equal length.

Front

What is the definition of a square?

Back

A square is a special type of parallelogram where all sides are equal and all angles are right angles.

Front

If a parallelogram has one right angle, what can be said about the other angles?

Back

If one angle is a right angle, all angles in the parallelogram are right angles.
