Practice problem
Which of the following is the Pythagorean theorem?
Area=Base×Height2\text{Area} = \frac{\text{Base}\times \text{Height}}{2}Area=2Base×Height
c2+b2=a2c^2+b^2=a^2c2+b2=a2 where a,ba,ba,b are the leg lengths and ccc is the hypotenuse.
a2+b2=c2a^2+b^2=c^2a2+b2=c2 where a,ba,ba,b are the leg lengths and ccc is the hypotenuse.
x=−b±b2−4ac2ax=\frac{-b\pm\sqrt{b^2-4ac}}{2a}x=2a−b±b2−4ac
Type a concept, like “slope” or “photosynthesis”.
