The legs of the triangle are labeled x and z.
The hypotenuse of the triangle is labeled y.
Explanation:
Step 1:
A right-angled triangle is a triangle with a 90° angle. The given triangle is right-angled.
The right-angled triangle has 3 sides. The hypotenuse, the opposite side and the adjacent side.
Step 2:
The hypotenuse is the longest side of the triangle and is always opposite to the 90° angle.
The two sides other than the hypotenuse are called the legs.
In the given triangle, the side opposite to the 90° angle is y, so y is the hypotenuse and the sides x and z are the legs.
