| Perimeter | The distance around a polygon, found by adding the lengths of the sides |
| Area | The number of square units needed to cover a region, found by multiplication |
| Volume | The number of cubic units needed to fill a solid figure, found by multiplication |
| Height | The dimension that must be multiplied by the length and width to determine volume |
| Exponent | The tiny raised number (a 2 or 3) that must be written next to the unit in area or volume |
| Line symmetry | The property of a figure that can be folded and the two parts will match |
| Line of symmetry | The vertical, horizontal, or diagonal line on which you fold a figure to get two matching sides |
| Congruent | Figures that have the same size AND shape |
| Similar | Figures that have the same shape but are NOT the same size |
| Asymmetrical | A figure that CANNOT be folded along a line so that the two parts will match |
| Slide | Also called a translation, sliding a figure in a straight line |
| Flip | Also called a reflection, flipping a figure over a line |
| Turn | Also called a rotation, turning a figure around a point or vertex |
| Transformation | A movement of a figure that does not change the size or shape |
| Apex | The point where the triangular faces of a pyramid meet |
| Translation | Sliding a figure in a straight line |
| Reflection | Flipping a figure over a line |
| Rotation | Turning a figure around a point or vertex |
| Complementary Angles | Two angles that add up to 90 degrees |
| Supplementary Angles | Two angles that add up to 180 degrees |
