Triangle Classification by SIDE LENGTHS ***Remember***When you look at a figure, you cannot assume segments are congruent on appearance. They must be marked as congruent. Ex 2) Classify EHF by its side lengths Classify EHG by its side lengths. Classify ACD by its side lengths. Example 3: Using Triangle Classification JKL. Find the side lengths of Find the side lengths of equilateral FGH. Example 4: Application A steel mill produces roof supports by welding pieces of steel beams into equilateral triangles. Each side of the triangle is 18 feet long. How many triangles can be formed from 420 feet of steel beam? Each measure is the side length of an equilateral triangle. Determine how many 10 in. triangles can be formed from a 100 in. piece of steel. 4-3 Angle Relationships in Triangles
