isosceles triangle
The congruent legs of an isosceles triangle are often referred to as the "sides" or "equal sides." These two sides are of equal length, which is a defining characteristic of isosceles triangles. The third side, which is not equal, is called the "base."
Are isosceles triangle sometimes an equilateral triangle
An obtuse triangle is not necessarily isosceles, but it can be.
No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.
An acute triangle can be an isosceles triangle, but it doesn't have to be. An isosceles triangle can be an acute triangle, but it doesn't have to be.

A right triangle and an isosceles triangle have the fact that they are both triangles in common. A right triangle can also be an isosceles triangle.
An isosceles triangle is a triangle that has two equal sides.
Are isosceles triangle sometimes an equilateral triangle
You cannot. An isosceles triangle cannot be scalene and a scalene triangle cannot be isosceles. So an isosceles scalene triangle cannot exist.
how is an isoscelels trapezoid related to a isosceles triangle
In an isosceles triangle and an isosceles trapezoid, both base angles are congruent
An obtuse triangle is not necessarily isosceles, but it can be.
A triangle that has one right angle and is isosceles is called an isosceles right triangle.
No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.
