Is isosceles triangle also an equilateral triangle?

Answer 1

An equilateral triangle has all sides measuring the same and an isosceles triangle has 2 sides congruent, so they are not the same.

Every equilateral triangle is also an isosceles triangle, but not every isosceles triangle is an equilateral triangle.

Isosceles = at least two equal sides

Equilateral = three equal sides

Answer 2

No because an isosceles triangle has only 2 equal sides whereas an equilateral triangle has 3 equal sides but they are both 3 sided triangles.

Answer 3

No, it is not.

Answer 4

No

Answer 5

No.
