What is a parallelogram?

Back

A parallelogram is a quadrilateral with opposite sides that are both parallel and congruent.

Front

What property do the diagonals of a parallelogram have?

Back

The diagonals of a parallelogram bisect each other.

Front

What is the definition of a rectangle?

Back

A rectangle is a parallelogram with four right angles.

Front

What is the definition of a rhombus?

Back

A rhombus is a parallelogram with all sides congruent.

Front

What is the relationship between rectangles and parallelograms?

Back

All rectangles are parallelograms, but not all parallelograms are rectangles.

Front

What is the condition for a quadrilateral to be classified as a rectangle?

Back

A quadrilateral is a rectangle if it has four right angles.

Front

Front

What does it mean for diagonals to be perpendicular in a parallelogram?

Back

If the diagonals of a parallelogram are perpendicular, it indicates that the parallelogram is a rhombus.

Front

If DF = 2x - 4 and EG = x + 8 in rectangle DEFG, how do you find x?

Back

Set DF equal to EG: 2x - 4 = x + 8, solve for x to find x = 12.
