306090 Triangle
1. The problem is to understand the side length ratios in a 30°-60°-90° right triangle.
2. A 30°-60°-90° triangle is a special right triangle where the angles are 30 degrees, 60 degrees, and 90 degrees.
3. The sides opposite these angles have consistent ratios: the side opposite 30° is the shortest, opposite 60° is medium length, and opposite 90° is the hypotenuse.
4. If we let the length of the side opposite the 30° angle be $x$, then:
\[\text{Opposite 30°} = x\]
5. The side opposite the 60° angle is $x \sqrt{3}$ because it is longer by a factor of $\sqrt{3}$.
\[\text{Opposite 60°} = x \sqrt{3}\]
6. The hypotenuse, opposite the 90° angle, is twice the shortest side:
\[\text{Hypotenuse} = 2x\]
7. Therefore, the side length ratios are:
\[1 : \sqrt{3} : 2\]
which correspond to the sides opposite 30°, 60°, and 90° angles respectively.
8. This ratio helps in solving many geometry and trigonometry problems involving these triangles.
