| Term | Definition |
|---|---|
| straight angle | An angle whose measure is exactly 180 degrees. |
| obtuse angle | An angle whose measure is > 90 and <180 degrees. |
| right angle | An angle whose measure is exactly 90 degrees. |
| acute angle | An angle whose measure is < 90 degrees. |
| supplementary angle | Two angles are supplementary if the sum of their measures is 180 degrees. |
| corresponding angel | Angles that occupy corresponding positions When a line intersects two other lines. When a line intersects two parallel lines, corresponding angles are congruent. |
| complementary angle | Two angles are complementary if the sum of their measures is 90 degrees. |
| congruent angles | Angles of the same measure. |
| verticle angles | When two lines meet at a point,the opposite angles. |
| adjacent angles | Two angles on a flat surface that share a common side and a vertex and do not overlap. |
| plane | A flat surface that extends without end. |
| acute triangle | A triangle with 3 acute angles. |
| right triangle | A triangle with a 90 degree angle. |

| square | A parallelogram with 4 right angles and 4 congruent sides. |
| rhombus | A parallelogram with 4 congruent sides. |
| isosceles triangle | A triangle with two congruent sides |
| equilateral triangle | A triangle with three congruent sides. |
| scalene triangle | A triangle with no congruent sides |
| diagonal line | A segment, other than a siide, that connects two vertices of a polygon. |
| perpendicular lines | Lines which meet to form four right(90 degree) angles |
| intersecting lines | Two lines that meet at a point. |
