To prove: Theangle PTQ is a right
Explanation of Solution
Given:
Therectangle is shown below:
Side PS is the geometric mean between ST and TR.
Calculation:
Consider side PQ,
Take square both sides as follows:
Thus, as the square of the side PQ is equal to the sum of squares of sides PT and QT, this proves the Pythagoras theorem. Hence, the angle PTQ is a right angle.
