The diagonals of an isosceles trapezoid are congruent in lengths
an isosceles trapeziod could be a quadrilateral because it has 4 sides and a quadrilateral has 4 sides
nope it is possible for a trapeziod to have three congruent sides
a trapeziod
trapeziod
a trapeziod
The base angles are congruent in an isosceles trapezoid
Opposites sides of an isosceles trapezoid are congruent
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
A trapeziod can have two names:a triangle and a trapeziod.A triangle because if you cut the trapeziod in half by its edges at a congruent angle,it will be two scalene triangles.
The legs are congruent.
No.
If it doesn't have congruent angles, it's not an isosceles triangle.
