Midsegments of Triangles

Front

What is a midsegment of a triangle?

Back

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

Front

What is the relationship between the length of a midsegment and the lengths of the sides it connects?

Back

The length of a midsegment is half the length of the side it is parallel to.

What is the formula to find the length of the opposite side using the midsegment?

Back

The formula is: 2(midsegment) = opposite side.

Front

If the midsegment of a triangle is represented as 5x - 1, how do you find the value of x?

Back

Set up the equation: 2(5x - 1) = opposite side, then solve for x.
