To determine whether the given lengths can be side lengths of a right angle
Answer to Problem 15CR
Given sides are of a right angle triangle.
Explanation of Solution
Given information:
22, 120, 122
Here we shall use the Pythagoras theorem.
According to Pythagoras theorem in any right angle triangle,
If the given sides satisfy the condition of Pythagoras theorem then they can be sides of right angle triangle.
Hence we check by putting values given,
Hence the given sides satisfy the condition. The sum of square of the two short sides is equal to the square of the largest side. Therefore given sides are of a right angle triangle.
