Understanding the Ratio in a Right Triangle for SAT Math Prep

Hey folks, I've been studying like crazy for the Math section of the SAT (not my strongest area, to be honest). I'm struggling to manage understanding ratios in right triangles. Any advice on how to gain a better understanding or any awesome resources you've used that break it down super clear? I'm really trying to nail this stuff down.

Hey there, it's fantastic that you're determined to nail these concepts down! The magic word in relation to ratios in right triangles is "Trigonometry". It's all about relationships between the sides and angles of right triangles. Here's a very basic overview to get started:

1. SOHCAHTOA: This acronym is a quick way to remember how to calculate ratios of sides in a right triangle. "SOH" stands for Sine = Opposite/Hypotenuse, "CAH" tells you that Cosine = Adjacent/Hypotenuse, and "TOA" is Tangent = Opposite/Adjacent.

2. Pythagorean Theorem: This formula (a² + b² = c²) relates the lengths of the sides of a right triangle.

As for resources, the College Board itself provides a good amount of review materials, including practice problems that should help. Practice is really the best way to grasp this concept. Try to solve a variety of problems involving right triangle ratios—everything from simple identification problems to more complex word problems.

Lastly, Khan Academy is also an excellent resource. Their lessons break down math concepts very clearly and you can find a lot of practice problems there as well. Stay focused and don't lose hope, soon you'll be nailing those questions!
