Question

Use the image to answer the question.

An obtuse triangle is drawn with vertices upper A upper B upper C.

Suppose a midsegment line XY¯¯¯¯¯¯¯¯
was drawn within △ABC
and it intersected lines CB¯¯¯¯¯¯¯¯
and AB¯¯¯¯¯¯¯¯
. If XY¯¯¯¯¯¯¯¯=16
units, what would be the length of AC¯¯¯¯¯¯¯¯
?

Answer 1

In triangle geometry, a midsegment connects the midpoints of two sides of a triangle and is parallel to the third side. The length of the midsegment is always half the length of the third side.

In your case, the midsegment \( \overline{XY} \) has a length of 16 units. According to the properties of midsegments:

\[
\overline{XY} = \frac{1}{2} \cdot \overline{AC}
\]

To find the length of \( \overline{AC} \), we can rearrange the equation:

\[
\overline{AC} = 2 \cdot \overline{XY}
\]

Now substitute the length of the midsegment:

\[
\overline{AC} = 2 \cdot 16 = 32
\]

Thus, the length of \( \overline{AC} \) is:

\[
AC = 32 \text{ units}
\]
