In the Pythagorean Theorem, what

does the "a" stand for?

a2 + b2 = c2

A. The longest side, or hypotenuse, of a right triangle.

B. One of the sides, or legs, that make up the right

angle.

C. Any unknown side of a right triangle.

The A stands for any of the sides or legs that make up a right angle so B is correct

B. One of the sides, or legs, that make up the right angle.

Step-by-step explanation:

The Pythagoras Theorem applies to the right-angled triangles. It is basically a relationship between the sizes of the all lengths of the triangle. The Pythagoras Theorem is given by:

C^2 = A^2 + B^2; where A and B are perpendicular and base respectively, and C is the hypotenuse. It is interesting to note that A can either be the perpendicular or the base of the right angled triangle. Same goes for B; it can be either the perpendicular or the base. Both the perpendicular and the base intersect at 90 degrees. But both cannot be the hypotenuse. Therefore, the variable A in the Pythagoras Theorem is one of the sides, or legs, that make up the right angle, i. e. Option B is the correct answer!
