Parallelogram and Trapezoids Practice

Front

What is a parallelogram?

Back

A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length.

Front

What are the properties of a parallelogram?

Back

1. Opposite sides are equal in length. 2. Opposite angles are equal. 3. The diagonals bisect each other.

Front

What is a trapezoid?

Back

A trapezoid is a quadrilateral with at least one pair of parallel sides.

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 midsegment of a trapezoid?

Back

The midsegment of a trapezoid is the average of the lengths of the two bases.

Front

If the bases of a trapezoid are 10 and 20, what is the length of the midsegment?

Back

The length of the midsegment is (10 + 20) / 2 = 15.

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

In a parallelogram, what is true about the diagonals?

Back

The diagonals of a parallelogram bisect each other.

Front

What is the formula for the area of a parallelogram?

Back

The area of a parallelogram is given by the formula: Area = base × height.

Front

If the base of a parallelogram is 5 cm and the height is 3 cm, what is the area?

Back

The area is 5 cm × 3 cm = 15 cm².
