Special Parallelograms

Front

What is a square?

Back

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

Front

What are the properties of a rhombus?

Back

A rhombus is a parallelogram with all four sides of equal length. Opposite angles are equal, and adjacent angles are supplementary.

Front

What is the relationship between the angles in a rhombus?

Back

In a rhombus, opposite angles are equal, and the sum of adjacent angles is 180 degrees.

Front

If the measure of one angle in a rhombus is 124 degrees, what is the measure of the adjacent angle?

Back

The adjacent angle would be 56 degrees, since adjacent angles in a rhombus are supplementary.

Front

What are the characteristics of a parallelogram?

Back

In a parallelogram, opposite sides are parallel and congruent, opposite angles are equal, and the diagonals bisect each other.

Front

What is the formula for the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula: Area = base × height.

Front

What is the difference between a rectangle and a rhombus?

Back

A rectangle has four right angles and opposite sides that are equal, while a rhombus has all sides equal but does not require right angles.

Front

Is a square a type of rhombus?

Back

Yes, a square is a specific type of rhombus where all angles are right angles.

Front

What is the measure of each angle in a square?

Back

Each angle in a square measures 90 degrees.

Front

If ABCD is a parallelogram, what can be said about the lengths of its diagonals?

Back

The diagonals of a parallelogram bisect each other but are not necessarily equal in length.
