ISOSCELES TRAPEZIUM –
If the oblique sides of a trapezium are equal, then it will be considered an isosceles trapezium.
Here, AB || DC and AD = BC
Property.1) The base angles of an isosceles trapezium are equal
In the figure, ∠A = ∠B, also ∠C = ∠D
Property.2) The diagonals are equal
In the figure, AC = BD
