Given that K, L and M are the points (-5, 0), (-2, 3) and (3, -2) respectively, prove that triangle KLM is right-angled.

• Yes, triangle KLM is right-angled.

• No, triangle KLM is not right-angled.

• Cannot be determined.

• None of the above

If AB and CD are produced (extended) will they meet at right angles?

• Yes

• No

• Cannot be determined

• Only if extended infinitely
