Angle PQR and angle SQR is said to form a linear pair.
And linear pair angles are 2 angles that form intersecting line. Now, we need to find the sum of their measurement.
=> Since it is a linear pair of Angle, the formula would be like this:
=> angle PQR + angle SQR = 180 degrees.
Thus, the sum of the two angles is 180 degrees.
Any linear pair of angles added will always be 180 degrees in total
