What is a midsegment of a trapezoid?

Back

The midsegment of a trapezoid is a line segment that connects the midpoints of the non-parallel sides. It is parallel to the bases and its length is the average of the lengths of the two bases.

Front

How do you find the length of the midsegment in a trapezoid with bases of lengths 28 and 16?

Back

The length of the midsegment is calculated as (28 + 16) / 2 = 22.

Front

What is the property of opposite sides in a parallelogram?

Back

In a parallelogram, opposite sides are equal in length.

Front

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

Back

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

Front

If one angle of a parallelogram is 60 degrees, what are the measures of the other angles?

Back

The opposite angle is also 60 degrees, and the adjacent angles are 120 degrees each.

Front

What is the relationship between the angles in a rhombus?

Back

In a rhombus, opposite angles are equal, and adjacent angles are supplementary (add up to 180 degrees).

Front

How do you calculate the value of x in a parallelogram if you know one angle is 58 degrees?

Back

Since opposite angles are equal, the opposite angle is also 58 degrees. The adjacent angles will be 180 - 58 = 122 degrees.

Front

What is the definition of a rhombus?

Back

A rhombus is a type of parallelogram where all four sides are of equal length.

Front

How do you find the measure of an angle in a rhombus if you know one angle is 54 degrees?

Back

The opposite angle is also 54 degrees, and the adjacent angles are 180 - 54 = 126 degrees each.

Front

What is the formula for the area of a parallelogram?

Back

The area of a parallelogram is calculated as Area = base × height.
