# A trapezium in which non-parallel sides and base angles are equal is called as an Isosceles Trapezium.
+
# The diagonals of an isosceles trapezium are equal.
+
# Area of isosceles trapezoid is given by<math>(a+b)/2 X h</math> , where a and b are the lengths of the parallel sides and h is the distance (height) between the parallel sides.
