Question

The coordinates of the vertices of are E (-4, 5), F (-1, 1), and G (3, 4). Determine whether EFG is a right triangle and support your decision. Show all work.

Answer 1

No, it will not be a right triangle

Explanation:

Since E (-4, 5) and F (-1, 1) are both in-plane one and G (3, 4) in-plane two

The x's are wrong for E and F which would be a cause for not a right triangle

And the y for G is not either 5 or 1 which would help make the triangle a right triangle.

So the triangle ends up being an scalene triangle and not a right triangle

Hopes this helps :)
