Open Ended

In your own words, explain the relationship between the area of legs a (3) and b (4) and the hypotenuse (5).

Multiple Choice

$$a^2\ +\ b^2\ =\ c^2$$

If you are solving for the length of the hypotenuse (c), after inserting the values of a and b into the equation, what is the FIRST step in solving for c ?

$$3^2\ +\ 4^2\ =\ c^2$$

• Add 3² + 4²

  7²

• Square (exponents)

  3² and 4²

  3x3 and 4x4

  9 and 16

Multiple Choice

$$a^2\ +b^2\ =\ c^2$$

$$3^2\ +\ 4^2\ =c^2$$

$$9\ +\ 16\ =c^2$$

What is the next step of the equation to solve for c?

• Add 9 + 16

• Subtract 16 from both sides

• Subtract 9 from both sides

Multiple Choice

What is the last step of the Pythagorean Theorem to solve for the length of the hypotenuse (c)?

$$25\ =\ c^2$$

• Divide both sides by 25

• Take the square root on both sides

Multiple Choice

$$a^2\ +\ b^2\ =\ c^2$$

$$15^2\ +\ b^2\ =17^2$$

$$225\ +\ b^2\ =289$$

After squaring both 15 (15x15) and 17 (17x17), what is the next step to solve for b² ?

• Add 225 to both sides

• Add 289 to both sides

• Subtract 225 from both sides

• Subtract 289 from both sides

Multiple Choice

After subtracting 225 from both sides of the equation, we get $$b^2\ =64$$

What is the last step to solve for b ?

• $$\sqrt[]{b}=\sqrt[]{64}$$

• $$\frac{b^2}{b}\ =\frac{64}{b}$$
