Problem 3: The two triangles are similar and the ratio of the lengths of their sides is equal to k: AB / A’B’ = BC / B’C’ = CA / C’A’ = k. Find the ratio BH / B’H’ of the lengths of the altitudes of the two triangles. Solution to Problem 3: If the two triangles are similar, their corresponding angles are congruent.
Similar Triangles Definition. Generally, two triangles are said to be similar if they have the same shape, even if they are scaled, rotated or even flipped over. The mathematical presentation of two similar triangles A 1 B 1 C 1 and A 2 B 2 C 2 as shown by the figure beside is: ΔA 1 B 1 C 1 ~ ΔA 2 B 2 C 2
Corresponding Sides. Triangles R and S are similar. The equal angles are marked with the same numbers of arcs. What are the corresponding lengths? The lengths 7 and a are corresponding (they face the angle marked with one arc) The lengths 8 and 6.4 are …

1. AA (Angle-Angle) The two angles of one triangle are equal to the two angles of the other triangle. ( AA rule) 2. SAS (Side-Angle-Side) Two sides are in the same proportion, and their included angle is equal. ( SAS rule) 3. SSS (Side-Side-Side) The three sides are in the same proportion. ( SSS rule ).
