So far I have this for 6. Isosceles 7. Scalene 8. Equilateral but for 9 thru 11 I'm not sure if I'm correct For 9 i got isosceles and 10.

**Classify the triangle by its angles and by its sides.**

**6.** A triangle with angles labeled as 30°, 75°, and 75°. The sides opposite the 75° angles are marked as congruent, indicating an isosceles triangle with acute angles.

**7.** A right triangle with a right angle (90°) indicated at one corner.

**8.** A triangle with two congruent sides marked and two congruent angles, indicating an isosceles triangle. Both angles appear to be acute.

**9.** A triangle with an obtuse angle labeled as 108°, making it an obtuse triangle.

**10.** A right triangle with a right angle marked at one corner.

**11.** A triangle with an angle labeled as 115°, indicating it is obtuse. The sides adjacent to this angle are marked as congruent, making it an isosceles triangle.
