Triangle Midsegment

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 triangle's midsegment and its parallel sides?

Back

The midsegment is parallel to the third side of the triangle and its length is half the length of that side.

Front

If a triangle has sides of lengths 10, 14, and 18, what is the length of the midsegment connecting the midpoints of the sides of lengths 10 and 14?

Back

The length of the midsegment is 9 (half of the third side, which is 18).

Front

How do you find the midpoint of a line segment?

Back

The midpoint is found by averaging the x-coordinates and the y-coordinates of the endpoints.

Front

What is the perimeter of a triangle if the lengths of its sides are 12, 16, and 20?

Back

The perimeter is 48 (12 + 16 + 20).

Front

If segment QR is a midsegment of triangle FGH, what can be said about segments FG and QR?

Back

Segment QR is parallel to segment FG and its length is half of FG.

Front

What is the measure of angle X if the other two angles in a triangle are 60 and 60 degrees?

Back

Angle X measures 60 degrees.

Front

If BD = 16, EA = 5, and FC = 3, what is the perimeter of triangle ABC?

Back

The perimeter is 48 (adding all sides of triangle ABC).

Front

What segment is parallel to EF in triangle FGH?

Back

Segment NP is parallel to segment EF.

Front

If x + 2 = 5, what is the value of x?

Back

x = 3.
