Question

I need stepwise solution for this I’ll mark you as the brainliest! Help me please

Answer 1

Step-by-step explanation:

Ques1. Given: AB//CD

To prove: anABP +anCDP=anDPB

Construction: draw line MN parallel to CD and AB.

Proof: anCDP=anDPN (alternate interior angles are equal then lines are parallel.)______1

similarly anABP=anBPN _______2

Now adding 1 and 2 (LHS and RHS)

anCDP+ anABP=anDPN+anBPN

anCDP+anABP=anDPB

Hence proved

Answer 2

Step-by-step explanation:

I hope this solutions help you .

Please give me a thanks.
