Question

Which is the best definition of an Isosceles Triangle ?

please help :(
A. A triangle that has at least two congruent sides

B. A triangle in which no two sides are congruent

C. A Triangle that has three congruent sides

Answer 1

A) but it is not a good choice.

Explanation:

I don't like A much. An Isosceles triangle has 2 congruent sides. If all three are congruent, it is equilateral.

Of the three choices however, it is A. B is a scalene triangle and C is as stated, equilateral.
