Aruna drew 3 lines, CD, KA, TP such that:
CD = KA
CD = TP
What is the relation between KA and TP?
TP + KA = 2 CD
TP = KA
Euclid's axiom states that - 'things which are equal to the same thing are equal to one another'. Hence CD = KA = TP.
Therefore,
KA + TP = CD + CD = 2 CD
Hence option B and C are correct.
