Pythagorean Theorem : States that if a triangle is a right triangle, then the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse or "a squared + b squared = c squared"
Pythagorean Triple : A set of non-zero whole numbers that satsify the pythagorean theorem equation
Elevation : Angle of ___ formed above a horizontal line
Depression : Angle of ___ formed below a horizontal line
Trigonometric Ratios : A name for sine, cosine, and tangent
Sine : Opposite over hypotenuse
Cosine : Adjacent over hypotenuse
Tangent : Opposite over adjacent
Sines : Law of ___ relates the sine of each angle to the length of the opposite side
Cosines : Law of ___ relates the cosine of each angle to the side lengths of the triangle
Law of SInes : This formula is (sin A / a)=(sin B / b)= (sin C / c)
Law of Cosines : This formula is "a squared = b squared + c squared - 2bc ( cos A)"
Area : The ___ of a triangle equals "1/2 bc (sinA)" given by SAS
