Answer: B. Andy is incorrect, because more than one triangle can be drawn with the given information.
Explanation:
Given: Andy wrote the following statement:
"You can only draw one unique isosceles triangle that contains an angle of 55°."
In isosceles triangle, there are two equal angles and one non-equal angle.
So, there is possibility of many isoceles triangles with 55°. It can be the measure of equal angles or non- equal angles.
hence, B is the right option. Andy is incorrect.
