HW 5-7 Trapezoids and Isosceles 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 is an isosceles trapezoid?

Back

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

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

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

Back

To find the measure of an angle in a trapezoid, use the property that the sum of the angles in any quadrilateral is 360 degrees.

Front

If one angle of a trapezoid is 115 degrees, what is the measure of the adjacent angle?

Back

The adjacent angle would be 65 degrees, since 115 + 65 = 180 degrees.

Front

What is the formula for the area of a trapezoid?

Back

The area of a trapezoid is given by the formula: Area = (1/2) * (b1 + b2) * h, where b1 and b2 are the lengths of the two parallel sides and h is the height.

Front

Can a trapezoid be a parallelogram?

Back

No, a trapezoid cannot be a parallelogram because a parallelogram has two pairs of parallel sides.

Front

What is the relationship between the bases of an isosceles trapezoid?

Back

In an isosceles trapezoid, the lengths of the bases are unequal, but the angles adjacent to each base are equal.

Front

How do you determine if a trapezoid is isosceles?

Back

A trapezoid is isosceles if the lengths of the non-parallel sides are equal.

Front

What is the height of a trapezoid?

Back

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