Find the sine of a 3 4 5 triangle

The video tutorial explains the concept of Pythagorean triples and their relation to right triangles. It emphasizes the importance of identifying right triangles when using trigonometry and the Pythagorean theorem. The tutorial further explores how to determine the smallest angle in a triangle, represented by theta, and calculates the sine of theta using the opposite side and hypotenuse. The example of a 3-4-5 triangle is used to illustrate these concepts, with a focus on understanding the relationship between the sides and angles of a right triangle.

What is a Pythagorean triple and how does it relate to right triangles?

Explain why the hypotenuse is always the longest side in a right triangle.

How do you determine the smallest angle in a right triangle?
