If an isosceles triangle ABC is dilated by a scale factor of 3, which of the following statements is not true?

AThe angles of ABC are congruent to the angles of A'B'C'.
BThe sides of ABC are congruent to the sides of A'B'C'.
CABC is similar to A'B'C'.
DA'B'C' is larger than ABC.

When a triangle is dilated by a scale factor, each side is multiplied by the same factor and angles are not modified. So the dilated triangle is a similar, larger triangle. So, the options b, c, and d are true, while option b, that the sides ABC are congruent to the sides of A'B'C' is not true. Congruent means equa and, when you dilate by a scale factor of 3, the sides will not be equal but larger. Then the answer is the option b.

Answer:

B
