Question

Verify that points P(-2,2) Q(2,2) and 4(2,7) are vertices of a right angled triangle.​

Answer 1

Answer:

Step-by-step explanation:

first of all find the distance between PQ and QR as well as PR

Then consider the greatest distance as the hypotenuse and check whether its square is equal to the sum of squares of the rest two distances (pythagoras theorem)

If it is equal then by converse of pythagras theorem the following points are vertices of right angled triangle

If it is not equal then they are not the vertices of right anglelled triangle..
