Solving Quadrilaterals

Front

What is a rhombus?

Back

A rhombus is a type of polygon that is a quadrilateral (four sides) with all sides of equal length. Opposite angles are equal, and adjacent angles are supplementary.

Front

If a rhombus has diagonals that bisect each other at right angles, what can be said about the lengths of the diagonals?

Back

The diagonals of a rhombus bisect each other at right angles, meaning they intersect at 90 degrees and each diagonal divides the rhombus into four right triangles.

Front

What is the formula for the area of a rhombus?

Front

In a rectangle, what is the relationship between opposite sides?

Back

In a rectangle, opposite sides are equal in length and all angles are right angles (90 degrees).

Front

What is the sum of the interior angles of a quadrilateral?

Back

The sum of the interior angles of a quadrilateral is 360 degrees.

Front

How do you find the measure of an angle in a parallelogram?

Back

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

Front

What is the relationship between the angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.

Front

If two angles are complementary, what is their sum?

Back

If two angles are complementary, their sum is 90 degrees.

Front

What is the measure of each angle in a square?

Back

Each angle in a square measures 90 degrees.
