Question | Answer |

If two shapes have exactly the same shape and size. | congruent |
A transformation which produces a figure similar to the original by proportionally shrinking or stretching the figure. | dilation |
A point that the graphs of two equations have in common. | point of intersection |
Movements of figures that preserve their shape and size. | rigid transformations |
Figures which have the same shape but are not necessarily the same size. | similar figures |
The point(s) where a graph intersects the y-axis. | y-intercept |
An educated guess that often results from noticing a pattern. | conjecture |
To make larger. | enlarge |
To make smaller. | reduce |
A transformation that turns all of the points in the original (pre-image) figure the same number of degrees around a fixed center point (such as the origin on a graph). | rotation |
A set of equations with the same variables. Solving means finding one or more solutions that make each of the equations in the system true. | system of equations |
Points, sides, edges, or angles in two or more figures that are images of each other with respect to a transformation. | corresponding parts |
An equation in two variables whose graph is a line. | linear equation |
A transformation across a line that produces a mirror image of the original (pre-image) shape. | reflection |
A ratio that compares the sizes of the parts of one figure or object to the sizes of the corresponding parts of a similar figure or object. In this course it is also referred to as the multiplier. | scale factor |
A transformation that preserves the size, shape, and orientation of a figure while sliding (moving) it to a new location (a slide). | translation |
