Question

An isosceles triangle is _________________ an equilateral triangle.

Sometimes
Always
Never

thanks

Answer 1

sometimes, I would go with that.

Answer 2

An isosceles triangle has 2 sides the same length and 2 angles the same size, always. An equilateral triangle has all 3 sides the same length. Each angle is 60 degrees, always.

Answer 3

An isosceles triangle is sometimes an equilateral triangle.

Isosceles means two of the sides are equal, and equilateral means three sides are equal, so an isosceles triangle is equilateral if and only if the third side is equal to the other two.

Answer 4

Never. An Isosceles triangle is a right triangle with two equal sides. An Equilateral triangle is a triangle with three equal sides.
Since the internal angles must total 180 degrees in any triangle, all equilateral triangles have equal angles of 60 degrees as well as equal sides. So a right triangle cannot possibly be an equilateral triangle.

Answer 5

And isosceles triangle has two equal sides. An equilateral triangle has 3 equal side.
SO and isoscleles triangle can NEVER be an equilateral triangle

Answer 6

Never. An equilateral triangle has three sides of equal length with an angle of 60 degrees in each corner. An isosceles triangle has two sides of equal length.

Answer 7

Sometimes.

Two sides are the same in an isosceles triangle. This does not exclude the third side also being the same.

Answer 8

never. an isosceles triangle has at least 2 equal sides, an equilateral triangle has at least 3 equal sides.

Answer 9

Sometimes

Answer 10

Isosceles ---> at least two congruent sides.
equilateral ---> three congruent sides.

So...
