Area of Trapezoids

Front

What is a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

Front

What are the bases of a trapezoid?

Back

The bases of a trapezoid are the two parallel sides.

Front

What is the formula for the area of a trapezoid?

Back

Area = (1/2) * (Base1 + Base2) * Height.

Front

What is the height of a trapezoid?

Back

The height of a trapezoid is the perpendicular distance between the two bases.

Front

In a trapezoid, the bases are always_________.

Back

parallel.

Front

If the bases of a trapezoid are 10 m and 20 m, and the height is 5 m, what is the area?

Back

Area = (1/2) * (10 + 20) * 5 = 75 m².

Front

What is the difference between a trapezoid and a parallelogram?

Back

A trapezoid has only one pair of parallel sides, while a parallelogram has two pairs of parallel sides.

Front

Can a trapezoid have congruent bases?

Back

Yes, if both bases are equal in length, the trapezoid is called an isosceles trapezoid.

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a trapezoid where the non-parallel sides are equal in length.

Front

What is the perimeter of a trapezoid?

Back

Perimeter = Base1 + Base2 + Side1 + Side2.
