Isosceles trapezium​

Answer 1

Answer:

Area: ½ x (sum of the lengths of the parallel sides) × height of the trapezoid

Perimeter: sum of top and bottom sides+2(leg of the trapezoid)

Number of vertices: 4

Number of edges: 4

Properties: Convex polygon, Cyclic

Type: Trapezoid, Quadrilateral

Line of symmetry: 1

In Euclidean geometry, an isosceles trapezoid is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid. Alternatively, it can be defined as a trapezoid in which both legs and both base angles are of the same measure.

Answer 2

Step-by-step explanation:

HI friend..

As a quadrilateral, the trapezoid is a four sided shape. The first unique property about the trapezoid is that it has only one pair of parallel sides. The trapezoid is also sometimes referred to as the trapezium. Trapezoids sometimes have different side lengths and different angle measures, but all the angles add up to 360 degrees as in any quadrilateral.

isosceles trapezoid is a quadrilateral having the following properties:

One pair of parallel sides (AB and DC)

One pair of congruent legs (DA and CB)

Base angles are congruent (m<D = m<C)

Diagonals are congruent (AC and BD)

Opposite angles are supplementary (their sum is 180 degrees)

m<A + m<C = 180; m<B + m<D = 180

hope it helps you........
