Question

AC meet CD and ab at D and e respectively c e and e are the bisectors of angle C and Angle A respectively such that angle 1 + angle 2 is equal to 90° prove that AB is parallel to CD​ it is very urgent of answer will be good I'll make your answer the brainliest

Answer 1

Answer:

Step-by-step explanation:

we know 1+2=90

and let ECD and EAB be x and y respectively

1+x=90 by linear pair        eqn1

2+y=90 same                    eqn 2

by adding eqn 1 and 2

1+2+x+y=180

hence prooved lines are parallel

as corresponding angles are equal

Answer 2

hope this helps you
