Answer:
Yes, the right angle is angle C.
Step-by-step explanation:
The given triangle has vertices at A(–2, 3), B(–3, –6), and C(2, –1).
Recall the slope formula;
The slope of the line going through AC is
The slope of the line going through BC s
The product of the slopes of AC and BC is
This means line AC is perpendicular to BC at C.
Hence the triangle ABC is right angled at C.
