Side lengths: 4cm, 4cm, 4cm 5. Angle measures: 60°, 60°, 60° 6. Angle measures: 30°, 60°, 90° 7. Angle measures: 20°, 145", 15° Name hey Date Period A. Equilateral Scalene Obtuse D Not a triangle E. Equiangular Isosceles 6. Right Classify each triangle by its angles and by its sides. 8. 59 59 62 Sides: Isosceles Angles: Acute 9. Sides: Isosceles Angles: Right 10. 120 Sides: Scalene Angles: obtuse 11. 12, 13. 85 45 50 Sides: Scalene Sides: Equilateral Sides: Scalene Angles: Right Angles: Equiangular Angles: aute Find the side lengths of each triangle. 14. ४ 2+5 8 3z - 1 15. 2x + 6.8 4z-4 8. 8x + 1.4 \\ underline x 1. aligned E / 0.\% 561 8 z + 5 = 3z - 1 60/2 = (2z)/2 3 = z 2x + 6.8 = 8x + 1.4 5,2| 6 = (6y)/6 0.9 = x 16. An isosceles triangle has a perimeter of 34 cm. The congruent sides measure (4x - 1) cm. The length of the third side is x cm. Find x. 4t ^ - 1 X 4x - 1 + 4x - 1 - x = 34 9x - 2 = 34 9x = 30 x = 4 cm Choose the best possible answer. 17. What is the side length of an equilateral triangle with a perimeter of 36 2/3 in? 31/12/20 B = 18 1/3 * in 36 2/3 . C. 12 1/3 . D. 12 2/9 . (360 2/3)/3 * 110/3 * 1/3 = 110/9 = 12 2/4 18.
