Answer:
An obtuse scalene triangle
Step-by-step explanation:
First, we calculate the length of the sides:
Side a – the distance between points B and C – is:
Side b – the distance between points C and A – is:
Side c – the distance between points A and B – is:
Then, we calculate the measure of the angles:
None of the sides are equal, so the triangle is not equilateral nor isosceles. None of the angles are 90°, so the triangle is not right. One of the angles is greater than 90°, so the triangle must be obtuse scalene.
