SB15 Midsegments in Trapezoids

Front

What is a midsegment in a trapezoid?

Back

The midsegment is a line segment that connects the midpoints of the non-parallel sides of a trapezoid.

Front

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

Back

The length of the midsegment is the average of the lengths of the two bases.

Front

What are the bases of a trapezoid?

Back

The bases are the two parallel sides of a trapezoid.

Front

What are the legs of a trapezoid?

Back

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

Front

If the lengths of the bases of a trapezoid are 10 and 18, what is the length of the midsegment?

Back

The length of the midsegment is (10 + 18) / 2 = 14.

Front

What is the relationship between the angles formed by the legs of a trapezoid?

Back

The angles formed by the non-parallel sides (legs) of a trapezoid are supplementary.

Front

What is the formula for the length of the midsegment (m) in terms of the bases (b1 and b2)?

Back

m = (b1 + b2) / 2.

Front

Can a trapezoid have equal legs?

Back

Yes, a trapezoid can have equal legs, in which case it is called an isosceles trapezoid.

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a trapezoid with non-parallel sides (legs) that 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.
