According to the Pythagorean theorem, which of the following statements below is true for the triangle in the diagram?


(1) a2+4 to 2 power= 5 2 power.

5

(2) a2-4 to2 power=5 2 power. A.

(3) a2+5 to2 power=4 2 power
(4) a2-5 to 2power=4 2 power. 4
(5) 5 2power +4 2power = a 2 power

What are the measurements in the diagram?

We use this symbol to show exponents ^.

a squared = a^2

Left side A

Bottom 4
Right side going up

Left a

Bottom 4
Right side going up 5

What is your answer?

Is the right side the hypotenuse?

Yes

It's the longest side

The hypotenuse is c in the Pythagorean Theorem.

a^2 + b^2 = c^2

a^2 + 4^2 = 5^2

Solve for a.
