| rectangle | a parallelogram with four right angles |
| square | a rectangle with four congruent sides |
| rhombus | a parallelogram with four congruent sides |
| trapezoid | a quadrilateral with exactly one pair of parallel sides |
| kite | a quadrilateral with two distinct pairs of adjacent congruent sides |
| line of symmetry | a line that divides a figure into congruent halves |
| translation (slide) | a transformation in which an image is formed by moving every point on a figure the same distance in the same direction |
| reflection (flip) | a transformation in which a figure is flipped over a line, called the line of reflection |
| rotation (turn) | a transformation in which an image is formed by turning its preimage about a point |
| congruent | two figures that have exactly the same size and shape |
| similar | two figures that have exactly the same shape but not necessarily the same size |
| cylinder | a solid bounded by two congruent |
| cone | a solid bounded by a circular base and a curved surface with one vertex |
| cube | a solid with six congruent square faces and every edge the same length |
| square pyramid | a solid whose base is a square and whose other faces are triangles that share a common vertex |
| rectangular prism | a solid in which all six faces are rectangles with three pairs of parallel, congruent, opposite faces |
| polygon | a closed plane figure made up of line segments |
| regular polygon | has sides of equal length and measure |
| polyhedron | a three-dimensional solid figure with flat surfaces |
| faces | the flat surface of a polyhedron |
| edge | The line segment where two faces intersect |
| vertex | The point where edges intersect |
| sphere | a solid figure having the surface equally distant from the center at all points |
| net | a plane figure which when folded gives you a solid figure |
| three-dimensional | An object that has height, width and depth, like any object in the real world. |
| two-dimensional | A shape that only has two dimensions (such as width and height) and no thickness. |
| A prism | a polyhedron, which means the cross section will be a polygon (a straight-edged figure) all sides will be flat |
