Question

if ABCD isa parallelogram with 2adjacebt angle <A=<B them the parallelogram is a​

Answer 1

Answer:

Sum of any two adjacent angles of a parallelogram is 180

o

.

Given, ∠A=∠B

∠A+∠B=180

o

⇒2∠A=180

o

⇒∠A=90

o

⇒∠A=∠B=90

o

Similarly ∠C=∠D=90

o

So, all angles are 90

∘

so it is a rectangle.
