Final answer:
Dilating a triangle changes the angles and side length of the triangle. Examples: If a triangle is dilated by a scale factor of 2, all of its side lengths are doubled.
Step-by-step explanation:
Dilating a triangle changes the angles and side length of the triangle. When a triangle is dilated, its angles remain the same, but its side lengths are multiplied by the same scale factor. For example, if a triangle is dilated by a scale factor of 2, all of its side lengths are doubled. This means that the angles of the triangle remain congruent, but the triangle becomes larger or smaller depending on the scale factor.
