Exploring 30-60-90 Triangle Relationships

This video tutorial explains the side length relationships in a 30-60-90 triangle. It covers how to find the hypotenuse and the longer leg when given the short leg, how to determine the short and long legs when given the hypotenuse, and how to calculate the short leg and hypotenuse when given the long leg. The tutorial includes examples and step-by-step calculations to help understand these geometric relationships.

What is the formula to find the hypotenuse in a 30-60-90 triangle?

• Hypotenuse = Long Leg / √3

• Hypotenuse = Short Leg × 2

• Hypotenuse = Long Leg × 2

• Hypotenuse = Short Leg × √3
