Trapezoid ABCD has vertices at A(2,1) B(12,1) C(9,4) and D(5,4). Which formula would help you find out if this trapezoid is isosceles? Is this an isosceles trapezoid?

Respuesta :

two sides are in equal lenght
If you have graphing paper graph the points and find out
but I already did it and it is an isosceles trapezoid
