Question

it abed is isoceles trapezium so that
AC² =Bc²+(ABX CD)
to prove​

Answer 1

Answer:

Step-by-step explanation:

Here, ABCD is isosceles trapezium.

An isosceles trapezium has a pair of parallel sides.

∴  AB∥CD

Its non parallel sides are  equal.

∴  AD=BC

Diagonals of an isosceles trapezium are equal.

⇒  AC=BD

Base angles of equal sides has equal angles.

∴  ∠C=∠D
