A triangle, a three-sided polygon, is formed by three line segments, called sides. These sides intersect at three points, called vertices. Each side has two vertices as endpoints, and the two sides that share a vertex form an angle. The side opposite the angle is called the leg of the triangle.
What is a Leg of a Triangle?
A leg of a triangle is one of the two sides that form the right angle in a right-angled triangle. In other words, it is a side that is perpendicular to the hypotenuse, which is the longest side of the triangle.
Here is a diagram of a right-angled triangle with the legs and hypotenuse labeled:

The legs of a triangle are often referred to as the “adjacent” and “opposite” legs. The adjacent leg is the leg that is adjacent to the angle that is being considered. The opposite leg is the leg that is opposite the angle that is being considered.
For example, in the diagram above, the leg that is adjacent to angle A is the leg that is labeled “a”. The leg that is opposite angle A is the leg that is labeled “b”.
The lengths of the legs of a triangle can be used to find the length of the hypotenuse using the Pythagorean theorem. The Pythagorean theorem states that:
a^2 + b^2 = c^2
where:
- a is the length of the adjacent leg
- b is the length of the opposite leg
- c is the length of the hypotenuse
The Pythagorean theorem can be used to solve for the length of any side of a right-angled triangle, provided that you know the lengths of the other two sides.
Question 1:
What constitutes a leg of a triangle?
Answer:
A leg of a triangle is a line segment that connects any two vertices of the triangle and does not contain the third vertex.
Question 2:
How many legs does a triangle have?
Answer:
A triangle has three legs, each connecting two vertices and not containing the third.
Question 3:
What is the relationship between the legs of a triangle?
Answer:
The legs of a triangle are the sides that are adjacent to each other, forming an angle at their point of intersection.
