Midsegments of Triangles and Angles

The length of a side of a triangle is 18 inches. What is the length of the midsegment that is parallel to it?

• 3 inches

• 9 inches

• 12 inches

• 15 inches

What is the midpoint of the segment whose endpoints are

(–2, –10) and (6, –4)?

• (2, 7)

• (-2, -7)

• (-2, 7)

• (2, -7)

Which is true about any midsegment in a triangle?

(Select all that apply.)

• The midsegment is parallel to its corresponding side.

• The midsegment is perpendicular to its corresponding side.

• The midsegment is half as long as its corresponding side.

• The midsegment connects the midpoints of two sides of a triangle.

• The midsegment is twice as long as its corresponding side.

A midsegment of a scalene triangle has a length of 12 in.
