Answer:
Option 2
Explanation:
We have to choose the statement which is always true about the angles of an isosceles triangle.
An isosceles triangle is a triangle that has two sides of equal length and has one vertex angle and two congruent base angles.
As opposite sides are equal
⇒ Two base angles are also equal by definition of isosceles triangle.
Hence, at least two of the angles of isosceles triangle are congruent.
Option 2 is correct.
