Warm Up 1. Given Triangle ABC, ∡A = 2x°, ∡B = x+5°, ∡C = 3x+7,° a. find the measurement of angle B. b. Is triangle ABC acute, obtuse, or right? Justify your answer. Labeling Triangles Rules for labeling Triangles: Sides of triangles are always labeled as __________________ letters. Angles of triangles are always labeled as __________________ letters The same letters are always ACROSS from each other!!! Let’s Try This! 1. Given triangle ABC, a = 25cm, ∠=74°, c = 15cm, ∠ = 20°,∠ = 86°, and b = 18cm. Draw and label the triangle below. Use your notes from 2-2 guide your thinking, and refresh your memory!
