Rhombus and Square

Front

What is a rhombus?

Back

A rhombus is a quadrilateral with all four sides of equal length and opposite angles that are equal.

Front

What is a square?

Back

A square is a special type of rhombus where all angles are right angles (90 degrees).

Front

What are the properties of a square?

Back

A square has all properties of a rhombus, rectangle, and parallelogram. It has equal sides, equal angles, and diagonals that bisect each other at right angles.

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

If one angle of a rhombus is 54°, what is the measure of the opposite angle?

Back

The opposite angle is also 54°.

Front

If two adjacent angles of a rhombus are 54° and x, what is the value of x?

Back

x = 126° (since adjacent angles in a rhombus are supplementary).

Front

What is the relationship between the diagonals of a rhombus?

Back

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

Front

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

Back

All angles in a square measure 90°.

Front

What is the formula for the area of a square?

Back

Area = side² (where 'side' is the length of one side of the square).

Front

What is the formula for the area of a rhombus?

Back

Area = (d1 * d2) / 2 (where d1 and d2 are the lengths of the diagonals).
