Question

1 In thegive figurse if AC = BD then prove
that AB = CD​

Answer 1

Answer:

you should atleast give the the figure them ask for solutions

Answer 2

Answer:

From the above figure  we get that

AC      = AB + BC

BD      = BC + CD

It is given that AC = BD

Plug the value of AC we get

AB + BC         = BC + CD                 … (1)

According to Euclid’s axiom,when equals are subtracted from equals, the remainders

are also equal.

Subtracting BC from both side in equation (1), we get

AB + BC − BC           = BC + CD − BC

AB       = CD
