Given:
m || QR
To find:
The measure of ∠QPR.
Solution:
Since m || QR and a transversal line intersect them, therefore the alternate interior angles are equal.
Let points S and T lie on the line m. S is on the right and T is on the left side of point P.
Now, angles TPQ, QPR and RPS lie on the one side of a straight line. It means, their sum is 180 degrees.
Therefore, the measure of angle QPR is 85 degrees.
