Find Sine Value Using Side Ratios

This lesson explains how the sine of an angle in a right triangle is determined by the ratio of the opposite side to the hypotenuse. It covers the properties of right triangles, including the identification of sides relative to reference angles. The lesson provides examples of calculating sine values for specific angles and emphasizes that sine values are consistent across similar triangles. It concludes by noting that sine applies to all triangles, with further exploration in future lessons.
