Handy Square Root Hacks
Handy Square Root Hacks is a skill on Pengi from Lesson 66: Special Right Triangles in Saxon Math, Course 3.
Key Concepts
Property To estimate measures, remember these approximations: $$ \sqrt{2} \approx 1.41 $$ $$ \sqrt{3} \approx 1.73 $$.
Examples A catcher's throw of $90\sqrt{2}$ feet is approximately $90 \times 1.41 = 126.9$ feet long. A triangle's height of $6\sqrt{3}$ inches is approximately $6 \times 1.73 = 10.38$ inches tall. An area of $36\sqrt{3}$ square inches is roughly $36 \times 1.73 \approx 62.28$ square inches.
Explanation Sometimes you need a real world number, not a funky square root symbol. Memorizing these quick approximations for $\sqrt{2}$ and $\sqrt{3}$ is like having a secret calculator in your brain. It helps you estimate lengths super fast, like figuring out if a baseball catcher's throw is as far as it looks. Just swap the symbol for the decimal!
