Question

1. what type of transformation does this represent? graph of coordinate plane with two triangles options: stretch, rotation, reflection, translation

Explanation:

The graph shows two congruent V-shaped figures where one is a mirror image of the other across a vertical line (likely the line of symmetry between them). A reflection transforms a shape into its mirror image over a line, which matches the visual pattern here. Stretch changes size, rotation turns the shape, and translation shifts it without mirroring—none of these fit.

Answer:

reflection
