Here is a simple way to remember the right triangle relationships: Hold up your left hand, palm facing out, fingers together and thumb sticking out the right like an L.

Now, imagine a line from the tip of your forefinger to the tip of your thumb. If you pretend the curve where your thumb meets your hand is a right angle, then you have a right triangle. Your thumb is a, your forefinger is b, and the imaginary line the hypotenuse is c.

Then the angle at the tip of your forefinger is A, the tip of your thumb is B and the right angle is C. Now, use that to memorize the following definitions:.

The trig cheat sheet only gives the formulas for these theorems. If you are required to use the full definition, or are unsure when to use each formula, you will need additional study material. Pythagorean Theorem, Law of Sines, Law of Cosines, Law of Tangents are all about the relationships between the sides and angles of triangles.

Using the definition of a right triangle on your hand as explained above the lengths of the sides are related by the following formula:. When the angle C is p, 0, or 2p, the law of cosines reduces to a simpler formula. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. Log in or sign up in seconds.
