Question

If AB=AC and CD=8CM and PQ=2 times AB. Are CD and PQ equal ? Which axiom is used for proving this?

Answer 1

We are given thatAB=4 cm, CD=8 cm and PQ=2 times AB.

Therefore,PQ=2×4=8 cm.

By the Euclid's axiom, which states that:" Things which are equal to the same thing are equal to one another."

CD and PQ are both equal to 8 cm, then CD=PQ.Hence, CD and PQ are equal.
