Greek Letters and Their Names

When you are working with geometry and trigonometry, you will see a lot of Greek letters. It will be helpful to know how the names of these letters are spelled and pronounced.

The Greek letters you are most likely to see for angles are α (alpha), β (beta), γ (gamma), δ (delta), and θ (theta). And of course you'll be using π (pi) all the time. Make sure you know how to spell and pronounce at least these six Greek characters.
