A right triangle can have at most 2 congruent sides, but may have no congruent sides. From the Pythagorean Theorem, the square of the hypotenuse will be equal to the sum of the squares of the other two sides - consequently the "other two sides must each be less than the length of the hypotenuse and thus not congruent with it. They can be congruent with each other however - which is what occurs in a 45°/45°/90° triangle (for any other right triangle, none of the sides will be congruent).
If it's an equilateral triangle then its 3 sides are congruent but if it's an isosceles triangle then only 2 of its sides are congruent
An isosceles triangle has exactly two sides which are equal. (The word congruent usually applies to triangles, not sides.)
an equilateral triangle has all equal sides
any triangle has 3 sides.

It has 2 congruent sides
how many congruent sides does a scalene triangle
An isosceles triangle has two congruent sides.
0 sides

2 sides
A congruent triangle has three sides, just like any other triangle. The term "congruent" in this context means that the lengths of the sides of the triangle are equal to each other. So, regardless of whether a triangle is congruent or not, it will always have three sides.
Equilateral, Isosceles and Scalene are three types of triangles classified based on how many congruent sides the triangle has.
