On a separate sheet of paper, identify if true or false. If false, explain why. 1. The length of any arc of a circle is equivalent to the circumference of that circle.

2. Rays and line segments have the same length.

3. Rays and line segments are part of a line.

4. A circle is a collection of points that are equidistant from a central point.

5. Rigid transformations preserve side length and angle measure.

6. Rigid transformations have the same size and the same shape.

7. Translations, reflections and rotations are rigid transformations.

8. In dilations, the image and pre-image of the shapes are congruent if the scale factor is 1.

9. A translation is a rigid motion that would carry one square onto another square and the
two squares would be congruent.

10. Perpendicular lines have opposite reciprocal slopes.
