In an isosceles triangle at least two sides are congruent but no angles are congruent.

Answer 1

The correct statement about an isosceles triangle is that it has at least two sides and two angles that are congruent, which are the defining characteristics of an isosceles triangle.

Step-by-step explanation:

The true statement among the given options about an isosceles triangle is: In an isosceles triangle at least two sides and two angles are congruent.

This is because, by definition, an isosceles triangle is one in which two sides are of equal length.

These two sides are known as the legs of the isosceles triangle, and the third side is known as the base.

The angles opposite the equal sides are also equal to each other, which are called the base angles.

Therefore, an isosceles triangle has at least two congruent sides and two congruent angles.
