Question

m is the midpoint of ad. what single transformation is required to map one of these congruent triangles onto the other? reflection rotation translation dilation

Explanation:

Step1: Recall transformation definitions

Reflection flips a figure over a line, rotation turns a figure around a point, translation slides a figure, and dilation changes the size of a figure.

Step2: Analyze congruent triangles

Since the triangles are congruent and have a common mid - point \(M\) of \(AD\), a reflection over the line passing through \(M\) and perpendicular to \(AD\) will map one triangle onto the other. Rotation would change the orientation in a different way, translation would just move the triangle without flipping it, and dilation is not applicable as the triangles are congruent (same size).

Answer:

Reflection
