What are the properties of the diagonals in a rhombus?

Back

In a rhombus, the diagonals are always perpendicular to each other and bisect each other.

Front

How can you prove that a parallelogram is a square?

Back

To prove a parallelogram is a square, you need to show that all sides are equal and the angles are right angles.

Front

What is the formula for the perimeter of a rhombus?

Back

The perimeter of a rhombus is calculated as P = 4a, where 'a' is the length of one side.

Front

What does it mean for diagonals to be congruent?

Back

Congruent diagonals are diagonals that are equal in length.

Front

What is the relationship between the angles of a rhombus?

Back

In a rhombus, opposite angles are equal, and adjacent angles are supplementary (add up to 180 degrees).

Front

What is the significance of perpendicular diagonals in a rhombus?

Back

Perpendicular diagonals in a rhombus indicate that the rhombus can be divided into four right triangles.

Front

What is a key property of the diagonals of a rectangle?

Back

In a rectangle, the diagonals are congruent but not necessarily perpendicular.

Front

How can you determine if a quadrilateral is a rhombus?

Back

A quadrilateral is a rhombus if at least one pair of opposite sides are equal and parallel, or if the diagonals bisect each other at right angles.

Front

What is the relationship between the sides of a square?

Back

In a square, all four sides are equal in length.
