One of the legs of the triangle shown in the picture is QL.
What are legs of a triangle?
The two sides of the triangle that intersect to determine the right angle are called legs of a triangle.
And the remaining side is called hypotenuse.
According to the given question
In ΔLQJ, we have
Right angle is at Q.
⇒ the sides LQ and QJ are intersecting each other to form right angle at Q.
Therefore, LQ and QJ are the legs of the given triangle LQJ.
Explanation for options
- ∠LJQ is an angle not a leg.
- Side LJ is not intersecting with other side to determine the right angle. So, LJ is not one of the leg of the given triangle.
- ∠QLJ is an angle not a leg.
- QL is one of the leg of the given triangle.
Hence, option D is correct. That is QL is the one of the legs of a triangle.
