Questions
- Which transformation maps a figure to a congruent figure?
- A translation maps each point (x, y) to (x + 3, y - 2). Where does the point (-1, 4) move?
- Which transformations always preserve both lengths and angle measures? Select all that apply.
- A side of a figure is 8 units long. Its corresponding side in a similar image is 12 units long. What is the scale factor from the original figure to the image?
- A dilation with scale factor 1/2 preserves angle measures but reduces the length of every nonzero segment to half its original length.
- Which statements describe properties of similar figures? Select all that apply.
- What transformation turns a figure around a fixed point?
- Triangle PQR is congruent to triangle XYZ in that order. If angle Q measures 68°, what is the measure of angle Y?
- If two figures are congruent, they are also similar with a scale factor of 1.
- Which statements about a reflection are true? Select all that apply.
