What is always true about the angles of an isosceles triangle? All three angles are congruent . At least two of the angles are congruent . The vertex angle is a right angle. The vertex angle is obtuse
All three angles are congruent . At least two of the angles are congruent. The vertex angle is a right angle. The vertex angle is obtuse Since it is given that AB ≅ AC it must also be true that AB = AC. Assume ∠B and ∠C are not congruent. Then the measure of one angle is greater than the other. If m∠B > m∠C then AC > AB because of the triangle parts relationship theorem. For the same reason if …

The two marked sides are both the same length. The two angles opposite these two marked sides are also the same: both angles are 70° . All three interior angles add to 180° because it is a triangle. An isosceles triangle has two equal sides and angles. These two equal sides will be marked with short lines.
