A rectangle is a parallelogram with four right angles and opposite sides that are equal in length.

Front

How is a square defined in relation to other quadrilaterals?

Back

A square is a quadrilateral that is both a rhombus and a rectangle, meaning it has equal sides and four right angles.

Front

What is the relationship between the diagonals of a rectangle?

Back

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

Front

What is the significance of adjacent sides in a rhombus?

Back

In a rhombus, adjacent sides are congruent, which is a defining property of this shape.

Front

What is the formula for the perimeter of a rhombus?

Back

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

Front

What is the relationship between the diagonals of a rhombus?

Back

The diagonals of a rhombus are perpendicular to each other and bisect each other.

Front

How can you prove that a parallelogram is a rhombus?

Back

A parallelogram can be proven to be a rhombus if one pair of adjacent sides is congruent or if the diagonals are perpendicular.

Front

What is the area formula for a rhombus?

Back

The area of a rhombus can be calculated using the formula A = (d1 * d2) / 2, where d1 and d2 are the lengths of the diagonals.
