Question

find the measure of qr

Explanation:

Step1: Use the mid - segment theorem

The mid - segment of a triangle is parallel to the third side and half its length.

Step2: Calculate the length of \(QR\)

Let the mid - segment be \(11\). According to the mid - segment theorem, if the mid - segment is half of \(QR\), then \(QR = 2\times11\).

Answer:

\(22\)
