Understanding trigonometric ratios is really important for working with angles, especially when we're dealing with everyday situations. Here’s why they matter:

• Sine (sin) helps us find the size of the opposite side compared to the hypotenuse in a right triangle.
• Cosine (cos) shows how the adjacent side relates to the hypotenuse.
• Tangent (tan) is the ratio of the opposite side to the adjacent side.

These ratios are used in many fields like engineering, physics, and even in computer graphics. They make it easier to solve problems with angles and help us make accurate calculations.
