Unit 6 Special Quadrilaterals Review Extra Practice

Front

What is a rhombus?

Back

A rhombus is a type of quadrilateral where all four sides are of equal length, and opposite angles are equal.

Front

What are the properties of a rhombus?

Back

1. Opposite angles are equal. 2. Adjacent angles are supplementary. 3. Diagonals bisect each other at right angles. 4. Diagonals bisect the angles.

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a trapezoid with at least one pair of parallel sides and the non-parallel sides (legs) are of equal length.

Front

What are the base angles of an isosceles trapezoid?

Back

The base angles of an isosceles trapezoid are congruent.

Front

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

Back

In a rhombus, the opposite angles are equal, and adjacent angles are supplementary. Use these properties to find unknown 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 two angles of a trapezoid are supplementary, what can be said about the other two angles?

Back

If two angles are supplementary, the other two angles must also be supplementary, as the sum of all angles in a trapezoid is 360 degrees.

Front

What is the relationship between the diagonals of a rhombus?

Back

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

Front

Can a trapezoid have two congruent sides?

Back

Yes, a trapezoid can have two congruent sides, making it an isosceles trapezoid.

Front

What is the measure of angle 2 if angle 1 is 108 degrees in a rhombus?

Back

Angle 2 would be 72 degrees, as opposite angles in a rhombus are equal.
