ProfessorTo prove a trapezoid is isosceles, you need to show that the legs (the non-parallel sides) are congruent. This can be done by demonstrating that the base angles opposite these sides are congruent. You can use the triangle congruence postulates or the properties of parallel lines and transversals to establish the equality of these angles.

Are diagonals of an isoceles trapezoid congruent?
Yes
How many congruent sides do isoceles trapezoid?
At least 2. (If all 3 sides are congruent it's equallateral, but can still be called isoceles)
What makes an isoceles trapezoid special?
The type of characteristics a trapezoid has or any other shape has makes it special in so many different ways
What does an Isociles trapezoid look like?
It looks like an isoceles triangle that has had its vertex cut off parallel to its base.
How do you make a triangle out of 3 trapezoids?
There is no combination of trapezoids which can form a triangle. well not exactly, if you have three " isoceles like trapezoid", then you can, provided, you are allowed to overlap. you should be able to figure it out now.... What if the triangle was equilateral and the trapezoids were isoceles? You wouldn't need the trapezoids to overlap. Use the longer 'bottom' edge of each trapezoid and the 'left' edge of the next trapezoid to make up the edge of the triangle. The shorter 'top' edge of the trapezoids touch the 'right' edge of the next trapezoid in the center of the triangle.
