parallel lines, angle and triangle classification, similarity vocab
| Term | Definition |
|---|---|
| similar triangles | triangles in which each pair of corresponding angles are congruent and each pair of corresponding sides are proportional |
| scale factor | ratio that describes the relationship between sides of similar figures |
| vertical angles | non-adjacent angles formed by opposite rays. these angles are always congruent (their measures are always equal) |
| linear pair | adjacent angles formed by the intersection of two lines. these angles are always supplementary (their measures always have a sum of 180 degrees) |
| right triangles | triangles in which one angle measures 90 degrees |
| acute triangles | triangles in which each angle measures less than 90 degrees |
| equilateral triangles | triangles in which all sides have equal measures |
| obtuse triangles | triangles in which one angle measures more than 90 degrees |
| scalene triangles | triangles in which no sides have equal measures |
| isosceles triangles | triangles in which two sides have equal measures |
| congruent triangles | triangles in which each pair of corresponding angles are congruent and each pair of corresponding sides are congruent |
