Triangle ABC, with vertices A(-2,0), B(6,2), and C(-1,4), is classified as a scalene triangle. All three sides (AB, BC, AC) and all three angles (
) are different.
To classify triangle ABC based on its sides and angles, we can use the distance formula to find the lengths of the sides and the slope formula to determine the angles.
Coordinates of Points:
- A(-2, 0)
- B(6, 2)
- C(-1, 4)

Classification:
- By Sides:
-
is a scalene triangle since all side lengths (AB, BC, AC) are different.
- By Angles:
-
is a scalene triangle since all angle measures (
) are different.
So,
is a scalene triangle based on both sides and angles.
