Answer:


image -- Not right triangle


image -- Not right triangle


image -- Right triangle

Step-by-step explanation:

Required

Determine whether the given points make a right triangle


image

First, calculate the distance between each point using:


image

So, we have:


image


image


image

From the above computations, the longest side is AB.

So;


image --- Test of Pythagoras


image


image


image

The above points do not make a right triangle


image

Calculate distance


image


image


image

From the above computations, the longest side is PQ

So;


image --- Test of Pythagoras
