🔵The SOHCAHTOA expression helps remember trigonometry formulas for sine, cosine, and tangent.

🟢Sine measures the ratio of the opposite side to the hypotenuse in a right triangle.

🟡Cosine measures the ratio of the adjacent side to the hypotenuse in a right triangle.

🟠Tangent measures the ratio of the opposite side to the adjacent side in a right triangle.

🔴Special right triangles, like the 3-4-5 triangle, can be used to find missing side lengths in right triangles.
