Trigonometric Proportions Worksheets

How to Evaluate Trigonometric Proportions? Sometimes learning trigonometric functions can become a tough job, especially if no one is able to understand its core concept. Nonetheless, resolving trigonometric functions deal with comparing similar right-angled triangles. In other words, if the triangles are proportional to each other, so will their corresponding angles. Let us look at the triangles below.

Triangle TCA

Triangle DOG

If you look at the triangles above, the side AT corresponds to the side OG, while CT corresponds with DG. Now let us consider the sides of the fractions.

You can now witness that the fractions are equal. This scenario will always occur in similar triangles.
