Graph the points. Then decide if AABC is acute, right, or obtuse. 9. A(-2,4), B(2,0), C(5,2)
1 answer:
The triangle ABC is a right angled triangle.
Explanation:
Given that the coordinates of the triangle ABC
The coordinates are A(-2,4), B(2,0) and C(5,2)
We need to determine the angle for the triangle ABC
Let us plot the coordinates in the graph and join them.
From the graph, it is obvious that in the triangle ABC, at angle B the triangle forms an angle 90°
Hence, the angle formed by the triangle ABC is right angled triangle.
Therefore, ABC is a right angled triangle.
