what is always true about the angles of an isosceles triangle?\nall three angles are congruent.\nat least two of the angles are congruent.\nthe vertex angle is a right angle.\nthe vertex angle is obtuse.
Answer
Brief Explanations:
An isosceles triangle has two equal - length sides. By the Isosceles Triangle Theorem, the angles opposite the equal sides are congruent. So, at least two of its angles are congruent. All three angles are congruent only for equilateral (a special case of isosceles), the vertex angle can be right, acute or obtuse.
Answer:
At least two of the angles are congruent.
