   An isosceles trapezoid’s interior angles add up to 360 degrees. The non-parallel sides of an isosceles trapezoid are congruent. The median runs parallel to both bases, and its length is equal to the sum of the bases’ lengths. “Trapezium” is another name for a trapezoid.

   Are the parallel sides of an isosceles trapezoid equal?

   • We know that a trapezoid is a quadrilateral with two parallel sides and two non-parallel sides. In an isosceles trapezoid, the non-parallel sides are equal. Thus, we can say that the parallel sides of an isosceles trapezoid are not equal and equal sides are not parallel. Two base angles in an isosceles trapezoid are equal to one another.

   What is a right angled isosceles triangle?

   • An isosceles triangle with angles of 90°, 45° and 45° is a right-angled triangle. This is the only combination of angles that is possible. All right-angled isosceles triangles will have these same angles. An obtuse-angled triangle has one angle that is greater than 90° and less than 180°.

   What is isosceles trapezoid?

   • Isosceles trapezoid is a trapezoid in which the top and bottom sides are parallel, while the remaining two non-parallel sides have the same length. We know that a trapezoid is a quadrilateral with two parallel sides and two non-parallel sides. In an isosceles trapezoid, the non-parallel sides are equal.

   How many sides does an isosceles triangle have?

   • An isosceles triangle has two sides that are equal in length. Isosceles means equal legs. The ‘legs’ are the two equal sides. The third side is called the base, even when the triangle is in a different orientation. An isosceles triangle has two angles that are the same size.

    In Euclidean geometry, an isosceles trapezoid (isosceles trapezium in British English) is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid.
