| Question | Answer |
|---|---|
| coordinate plane | a plane formed by the intersection of a horizontal number line (x-axis) with a vertical number line (y-axis) |
| x-axis | the horizontal axis (side to side) |
| y-axis | the vertical axis (up and down) |
| ordered pair | a point in the coordinate plane named (x,y) |
| origin | the point where the x-axis and the y-axis meet; (0,0) |
| translation | a movement (slide) of a figure along a straight line |
| reflection | a change in position of a figure that flips the figure across a line |
| dilation | a change in the size of a figure which either reduces or enlarges the picture |
| rotation | a change in position of a figure around a fixed point |
| similar figures | figures that are the same shape, but are a different size;all of the corresponding parts of the figures have the same ratio |
| congruent figures | figures that are the exact same shape and size |
| parallel lines | two or more lines in the same plane that never intersect |
| transversal | a line that intersects at least two other lines |
| corresponding angles | a pair of angles at matching intersections of the parallel lines and the transversal |
| alternate interior angles | a pair of angles in between the parallel lines that are on the opposite sides of the transversal |
| alternate exterior angles | a pair of angles outside the parallel lines that are on the opposite sides of the transversal |
| same side interior angles | a pair of angles in between the parallel lines that are on the same side of the transversal |
| sequence of transformations | a set of transformations (translations, reflections, dilations, and rotations) in the coordinate plane that must occur in a specific order to obtain a new figure |
