An equilateral triangle is an isosceles triangle?

Question

sometimes,always or never

Answer 1

An equilateral triangle is ALWAYS an isosceles triangle

since the definition of an isosceles triangle is that it has AT LEAST two congruent sides, and an equilateral triangle always has three congruent sides, - three is at least two

Answer 2

Yes, sure. A triangle is equilateral if all of its 3 side s are equal, and is isosceles if it has (at least) 2 equal sides. So, every equilateral triangle is isosceles.

Answer 3

Hey there!

The answer to your question is always. In the equilateral triangle, all sides are equal. In the isoceles triangle, 2 or more sides are equal. Always.

Try to check the angle measures of the triangle. Equilateral triangles always have equal angle measures i.e. 60 degrees. Isoceles triangle has at least two equal angle measures. Always.

Answer 4

Always. An equilateral triangle has 3 equal sides. It therefore always has 2 equal sides.
