Question

Select all the transformations that do not preserve distance but preserve angle measure. Reflection across the line y=x Translation of 3 units upwards Counterclockwise rotation of 180° about the origin Dilation by a scale factor of 0.5 about the origin Dilation by a scale factor of 2 about the point (1, 1) Translation of 2 units to the right then dilation by a scale factor of 1.5 about the point (1, 1)​

Answer 1

Explanation:

Reflection , translation, rotation preserve distance and angle measure.

Dilation with a scale factor not equal to 1 or -1 do not preserve distance but preserve angle measure.

Answer is:

• Dilation by a scale factor of 0.5 about the origin
• Dilation by a scale factor of 2 about the point (1, 1)
• Translation of 2 units to the right then dilation by a scale factor of 1.5 about the point (1, 1)​
