1. a triangle is graphed on a coordinate grid. which transformation will result in a triangle that is not congruent to the original triangle?

a 180° counterclockwise rotation around the origin.
a reflection over the y - axis
a dilation by a scale factor of 4.
a translation 5 units to the left.

Explanation:

Congruent figures have identical shape and size. Rotations, reflections, and translations are rigid transformations that preserve side lengths and angles, keeping figures congruent. Dilation changes the size of the figure by a scale factor, so it does not preserve congruence.

Answer:

C. A dilation by a scale factor of 4.
