Trapezoids

Front

What is a trapezoid?

Back

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

Front

How many pairs of parallel sides does a trapezoid have?

Back

A trapezoid has exactly 1 pair of parallel sides.

Front

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

Back

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

Front

What is the formula for finding 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 parallel sides.

Front

If one angle of a trapezoid is 110 degrees, what is the measure of the adjacent angle if the trapezoid is isosceles?

Back

The adjacent angle would be 70 degrees.

Front

In an isosceles trapezoid, what can be said about the non-parallel sides?

Back

The non-parallel sides (legs) of an isosceles trapezoid are equal in length.

Front

What is a diagonal in a trapezoid?

Back

A diagonal in a trapezoid is a line segment that connects two non-adjacent vertices.

Front

How do you find the length of a diagonal in a trapezoid?

Back

The length of a diagonal can be found using the distance formula or by applying the Pythagorean theorem in certain cases.

Front

What is the relationship between the angles of a trapezoid?

Back

The angles on the same side of a trapezoid are supplementary, meaning they add up to 180 degrees.
