Solution

Solution Steps

Step 1: Identify the Transformation

The triangle ETM has been transformed to create triangle E'T'M'. Visually, it appears to have been rotated.

Step 2: Determine the Center of Rotation

The intersection of segments MM' and TT' would be the center of rotation if they were perpendicular bisectors of each other. However, the provided grid makes it visually clear they aren't. The lines appear to cross very close to the origin (0,0), so let's assume that is the center of rotation.

Step 3: Determine the Angle of Rotation

The image suggests a rotation of 90 degrees clockwise about the origin. If E, T and M were rotated 90 degrees clockwise about the origin they would land very close to the positions marked for E', T' and M' respectively.

Final Answer

Rotation of 90 degrees clockwise about the origin (0,0).
