Only two equal side lengths
that's an iscoceles triangle...
Isosceles.
A triangle with 2 equal side lengths is called an isosceles triangle.
You must have more information to determine what type of triangle it is. If two of the lengths are equal, it is isosceles. If all three of the lengths are equal, it is equilateral. If none of them are equal, it is scalene. It may also be a right triangle if it is isosceles or scalene.
A triangle with no equal side lengths is a scalene triangle.
Only two equal side lengths
A scalene triangle which has different side lengths
that's an iscoceles triangle...
Lengths of: equal side+equal side+base = perimeter
Isosceles.
A triangle with 2 equal side lengths is called an isosceles triangle.
I would place this triangle in the category of isosceles triangles, because the 10m side and the 10m side have equal lengths.

In a triangle, if all of the angles are 60 degrees, then all three sides of the triangle are equal to each other. Basically, if the angles are equal than the sides must be equal. This kind of triangle is called an equilateral triangle.
