  1. . #18 . . ~ . Name: Period: For questions 1 through 4 use the word bank to correct identify each special triangle segment. Altitude Angle Bisector Median Perpendicular Bisector # 2 # 3 # 4 # 1 4 cm Classify the triangle to the right based on its sides and angles: # 5 5 cm 3 cm Use the slope formula to determine the slope of the line containing the points (-3, 6) and (5, -12). #6 # 7 Using the slope from question #6, identify the perpendicular slope of the line. Solve for x: 13 – 3x = x + 5 # 8 What is the slope of the following equation: 4x + 5y = - 20 # 9 B Given the figure to the right, what is the length of DE? # 10 E D A C 6 cm
