In an isosceles triangle, the angles opposite the congruent sides are equal. Since triangle ABC is isosceles with sides AC and AB being congruent, the angles opposite these sides (angles B and C) must be equal.
Therefore, the correct statement about the measure of angle B is:
**It is equal to the measure of angle C.**
Therefore, the correct statement about the measure of angle B is:
**It is equal to the measure of angle C.**
