One more because an equilateral triangle has 3 equal sides whereas a right isosceles triangle has only 2 equal sides.
All triangles have 3 sides but an isosceles triangle has 2 equal sides and an equilateral triangle has 3 equal sides.
Using the traditional definitions, a triangle that has two equal sides (and angles) is an isosceles triangle and one with three equal sides (and angles) is an equilateral triangle. However, some mathematicians define an isosceles triangle as any triangle having at least two equal sides, which is what you are describing.
if you mean ALL sides equal then no, because for a triangle to have ALL equal sides all angles must be equal (60 degrees), and an obtuse triangle must have an angle with 91 or more degrees. but if you mean TWO sides equal then yes. for example, a triangle with angles 40, 40 & 100 degrees would have two equal sides.

A triangle with 2 equal sides is known as an isosceles triangle. Sometimes it is defined as a triangle with 2 or more equal sides, which therefore includes equilateral triangles as a type of isosceles.

A triangle. To be more specific, an equilateral triangle.

There are two definitions of isosceles, one of which defines it as a triangle with exactly two equal sides, which excludes equilateral triangles. The other definition is a triangle with two or more equal sides and therefore is inclusive of equilateral triangles.
An obtuse triangle.
