Answer: It is number A
Step-by-step explanation: n 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.
Area: ½ x (sum of the lengths of the parallel sides) × height of the trapezoid
Perimeter: the sum of the 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
