Yes if the isosceles triangle is a right isosceles triangle because that leg opposite the hypotenuse is the height

No, an isosceles triangle can not be a right triangle, because a right triangle has an angle of 90 degrees angle, and two angles of 45 degrees. An isosceles triangle has all acute angles, therefor, making it an acute triangle, so no, an isosceles triangle is not, i repeat not, a right triangle.

Isosceles triangle have two equal angles2

An equilateral TRIANGLE is not an isosceles ANGLE. However, all equilateral triangles are isosceles triangles. By definition, an isosceles triangle has at least two sides that are congruent. An equilateral has three sides that are congruent, thus an equilateral triangle is an isosceles triangle.

An isosceles triangle.

Are isosceles triangle sometimes an equilateral triangle

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.

You cannot. An isosceles triangle cannot be scalene and a scalene triangle cannot be isosceles. So an isosceles scalene triangle cannot exist.
