SB15 Midsegments in 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 parallel sides of a trapezoid are called the bases.

Front

What are the legs of a trapezoid?

Back

The non-parallel sides of a trapezoid are called the legs.

Front

What is the midsegment of a trapezoid?

Back

The midsegment is the line segment that connects the midpoints of the legs of a trapezoid.

Front

How do you calculate the length of the midsegment in a trapezoid?

Back

The length of the midsegment is the average of the lengths of the two bases: (Base1 + Base2) / 2.

Front

What is the relationship between the midsegment and the bases of a trapezoid?

Back

The midsegment is parallel to the bases and its length is the average of the lengths of the bases.

Front

What do we call the angles formed by the legs of a trapezoid?

Back

The angles formed by the legs of a trapezoid are called base angles.

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 significance of the midpoints of the legs in a trapezoid?

Back

The midpoints of the legs define the endpoints of the midsegment.

Front

Are the diagonals of a trapezoid related?

Back

The diagonals of a trapezoid are not related.
