|---|
| equalateral | all sides are the same length |
| polygon | a shape with many sides |
| isosceles | two sides of a triangle equal the same |
| parallel sides | lines that never intersect and is the exact same distance apart |
| triangle | a shape with three sides and three angles |
| acute | an angle less than 90 degrees |
| obtuse | an angle more than 90 degrees |
| right | an angle that is 90 degrees |
| rectangle | a four sided parallelogramwith only right angles |
| parallelogram | a shape with two sets of parallel lines |
| quadrilateral | a four sided shape |
| line of symetry | a shape that can be split in half and be the same on either side |
| scalene | a triangle that all of its sides are different lengths |
| rhombus | a parallelogram with four even sides, four angles |
| trapezoid | a four sided, four angled shape with one set of parallel lines |
| rotational symmetry | a shape that when you rotate it, it will stay the same |
| tessellation | a tiling made up of copies of the same shape or shapes that fit together |
| transformation | movements of geometric figures |
| perpendicular | when you have two lines that intersect at a right angle |
| dilation | when you have a shape or picture and you enlarge it or shrink it to a certain size. |
| rotation | when u have something like a shape and u turn it to a different side |
| transversal | when a line intersects two parallel lines |
| reflection | when u have something and u flip it to make the same shape |
| similar triangles | two triangles that are similar but not exactly the same |
| congruent triangles | all sides and angles in a triangle are equal |
| vertical angles | congruent angles formed by the intersection of two lines |
| translation | one type of transformation where a figure is slid horizontaly, verticly, or both |
| supplementarry angles | two angles on a line that add up to 180 |
| ASA congruence | If you have two triangles with two angles and the included side and they are the same |
| SAS congruence | In two triangles, two sides and the included angle are the same |
| SSS congruence | In two triangles, each side is the same as the same side on a different triangle. Example: Line AB on triangle 1 is the same as line FG on triangle 2 |
| Coresponding Angles | Angles that are in the same spot but ower on a transversal side |
| Alternate Exterior Angles | Angles that are alternate on the outside of parrallel lines |
| Alternate Interior angles | Angles that are on the inside of transversal and Parrallel lines |
| Complementary Parts | Parts of congruent triangles that match |
