M4D2 Special Parallelograms Practice

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

What are the properties of a rhombus?

Back

A rhombus is a type of parallelogram where all four sides are of equal length, opposite angles are equal, and the diagonals bisect each other at right angles.

Front

How do you find the value of x in a parallelogram when given angles?

Back

In a parallelogram, opposite angles are equal, and adjacent angles are supplementary (add up to 180 degrees). Use these properties to set up equations to solve for x.

Front

What is the relationship between the diagonals of a rectangle?

Back

In a rectangle, the diagonals are equal in length and bisect each other.

Front

How do you calculate the area of a parallelogram?

Back

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

Front

What is the definition of a rectangle?

Back

A rectangle is a parallelogram with four right angles.

Front

What is the significance of the diagonals in a rhombus?

Back

The diagonals of a rhombus bisect each other at right angles and also bisect the angles of the rhombus.

Front

How do you determine the length of a side in a rectangle if the area and one side length are known?

Back

If the area (A) and one side length (l) are known, the length of the other side (w) can be found using the formula: w = A / l.

Front

What is the formula for the perimeter of a parallelogram?

Back

The perimeter of a parallelogram is calculated using the formula: Perimeter = 2 × (base + height).

Front

What is the difference between a rhombus and a square?

Back

A rhombus has all sides equal and opposite angles equal, while a square has all sides equal and all angles equal to 90 degrees.
