Similar Triangles and Ratios - Math Plane

Similar triangles: Side - Angle - Side Definition: If a pair of coresponding sides of 2 triangles have the same ratio AND the included angles are congruent, then the triangles are similar. A DEF ratio of 2 sides are equal, & non-included angles are congruent but, triangles are not similar! Comments: Example: A ABC

Law of Cosines What is it? Equations that relate the interior angles of a triangle to their coresponding (opposite) sides. In a triangle, "two known sides and the included angle can determine the length ofthe 3rd side' Law of Cosines a b Examples: — 2bc(cosA) — 2ac(cosB) — 2ab(cosC) 1) Given the following triangle, find the length of d.
