PRACTICE: MIDSEGMENTS

Front

How many midsegments does a triangle have?

Back

3

Front

If AC=42, find DF.

Back

DF = 21 (DF is half the length of AC, which is the property of midsegments.)

Front

Complete the statement: the midsegment of a triangle is half the length of the ___ ____ to it.

Back

side parallel

Front

Find DE if DE is a midsegment connecting two sides of a triangle.

Back

DE = 7 (DE is half the length of the side it is parallel to.)

Front

What is a midsegment in a triangle?

Back

A midsegment is a line segment that connects the midpoints of two sides of a triangle.

Front

What is the relationship between a midsegment and the sides of a triangle?

Back

A midsegment is parallel to the third side and half its length.

Front

If a triangle has sides of lengths 10 and 14, what is the length of the midsegment connecting these two sides?

Back

The length of the midsegment is 12 (the average of the two sides).

Front

How do you find the length of a midsegment?

Back

To find the length of a midsegment, take half the length of the side it is parallel to.

Front

If the midsegment of a triangle is 5, what is the length of the side it is parallel to?

Back

The length of the side is 10 (since the midsegment is half the length of the side).

Front

What is the significance of midsegments in triangle similarity?

Back

Midsegments create similar triangles when drawn in a triangle.
