Right ankle is exactly 90 degrees, while obtuse is more than, and acute is less than
The true statement is (c) No; the slopes of segment EF and segment DF are not opposite reciprocals.
<h3>Right triangles </h3>Right triangles have a pair of perpendicular lines
Coordinates
The coordinates are given as:
- D = (-2,-1)
- E = (-2,2)
- F = (0,0)
Start by calculating the slopes of lines DF and EF using:
So, we have:
Also, we have:
For the triangle to be a right triangle, then the calculated slopes must be opposite reciprocals.
i.e.
By comparison, the slopes of both lines are not opposite reciprocals.
Hence, the true statement is (c)
