Question

In Quadrilateral ABCD, AB|| CD and ADllBC prove that < ABC =<ADC​

Answer 1

Answer:

Step-by-step explanation:

If AB║CD AND AD║BC  

Then the figure would be a square.

All the angles in a square are of equal measure (90°).

Thus, we can say that ∠ABC=∠ADC.

               OR

If it is a rhombus.

Then we observe that ∠ABC AND ∠ADC are opposite angles.

Opposite angles in a rhombus are equal.
