Question

the base angles of icocesles trapejium are equal or not.?prove​

Answer 1

$\Large{\underline{\underline{\sf \red{Answer:-}}}}$

We know opposite sides are equal in an Isosceles trapezium. We know the diagonals are equal in an Isosceles trapezium. So, we can say that by (side-side-side) SSS congruency the two triangles are congruent. Hence proved that base angles are equal.
