In a trapezoid of the vector BC = AD . We will, then find that P = AC + BD is collinear with AD . If P = AD , then

Options

  1. A= +1
  2. B= +1
  3. C+ =1
  4. D=2+

Correct answer

A. = +1

Step-by-step solution

We have, aligned & P = AC + BD = AC + BC + CD = & AC + AD + CD = AD +( AC + CD ) = & AD + AD =( +1) AD aligned But, P = AD = +1
