Slope of AB=(2-3)/(1+1)=-1/2; AC=(-1-3)/(-3+1)=-4/-2=2; BC=(-1-2)/(-3-1)=-3/-4=3/4.
The product of two sides that are perpendicular is -1. Slopes of AB and AC are perpendicular so angle A is a right angle. ABC is a right-angled triangle.

2. no
3. no
4.yes
Step-by-step explanation:
1. if you solve this you will get -11/120 and you want 3/7
2. no because you will get 5/16 and you want 5/8
3. no because you will get 3/8 and you want 5/8
4. yes because you will get 5/8
