(image of a triangle with points a, b, c, d and label exterior angle-)

Explanation:

Step1: Analyze each term

• 5. Triangle with 3 ≅ sides: Equilateral triangle (C)
• 6. Triangle with 3 angles less than 90: Acute triangle (D)
• 7. Triangle with 1 angle = 90: Right triangle (G)
• 8. Triangle with at least 2 ≅ sides: Isosceles triangle (F)
• 9. Triangle with no ≅ sides: Scalene triangle (E)
• 10. Angle formed by extending the sides of a triangle: Exterior angle (H)
• 11. Triangle with 3 ≅ angles: Equiangular triangle (B)
• 12. Triangle with one angle greater than 90: Obtuse triangle (A)

Step2: Match each number to the correct letter

5 - C, 6 - D, 7 - G, 8 - F, 9 - E, 10 - H, 11 - B, 12 - A

Answer:

1. C. Equilateral
2. D. Acute triangle
3. G. Right triangle
4. F. Isosceles triangle
5. E. Scalene triangle
6. H. Exterior angle
7. B. Equiangular
8. A. Obtuse triangle
