triangle
A traingle has ISOSCELES.
I learned about isosceles triangles in school last Thursday.

If you can only prove two sides of an apparently equilateral triangle to be congruent then you have to use isosceles.
You will also need the angles so that you can use the Isosceles Triangle Theorems to solve for the base of isosceles triangle when only two sides are given.
use protractor, or divide isosceles triangle into two right triangles, and use trigonometric functions to find the angles individually (ONLY IF YOU HAVE ALL SIDE LENGTHS CAN YOU DO THIS)
It depends on isosceles WHAT? There are isosceles triangles, isosceles trapezia, for example.
In an isosceles triangle and an isosceles trapezoid, both base angles are congruent
If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle.If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle.If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle.If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle.
