What is the hypotenuse in a right triangle?

• The longest side of the triangle

• The side adjacent to the right angle

• The shortest side of the triangle

• The side opposite the right angle

How is the opposite leg of a right triangle determined?

• It is always the shortest side of the triangle

• It is the side across from the angle of perspective

• It is the side across from the right angle

• It is the longest side of the triangle

In the context of trigonometry, what does the adjacent side refer to?

• The longest side of the triangle

• The side across from the right angle

• The side opposite to the angle of interest

• The side next to the angle of interest and forming the right angle
