- Some special right triangles may require you to simplify
radical expressions.
- The symbol for a radical is
√.
- You cannot leave a radical in the
denominator of a fraction.
- Therefore, you need to
rationalize the
denominator.
Practice multiplying and dividing radicals:
1. $\frac{5\sqrt{2}}{2}$
2. $\frac{2\sqrt{3}}{3}$
3. $2\sqrt{2}$
4. $\frac{14\sqrt{3}}{3}$
5. $5\sqrt{3}$
More Examples: Find all missing side lengths.
1. Legs: $\frac{5\sqrt{2}}{2}$
2. Opposite 60°: $2\sqrt{3}$, Hypotenuse: 4
3. Opposite 30°: 3, Hypotenuse: $6\sqrt{3}$
4. Legs: $4\sqrt{2}$
5. Legs: $5\sqrt{2}$
6. Side opposite 30°: $\frac{q}{2}$, Side opposite 60°: $\frac{q\sqrt{3}}{2}$
