Right Triangle Trigonometry

Pythagorean theorem

Formula = a2 + b2 = c2

Opposite= the opposite side from a angle.

Adjacent= Oppostie from the hypotenuse.

hypotenuse= Longest side.

Sine and Cosine Ratios

SOH CAH TOA

Tan(a) = opp/hyp

Tan = Tangent

cos = adj/hyp

Cos = Cosine

Sin = opp/hyp

Sin = Sine

Trigonometry

How to solve =

locate the degree of angle A , while given the alternative side and hypotenuse. From perspective A , the sides opposite and hypotenuse are given. consequently, use the sine trigonometric characteristic. (Soh from Soh Cah Toa) Write the equation and remedy using the inverse key for sine.

Used to calculate lengths of side and measures of angles in a triangle.

= Triangle measurements.

Angle Of Elevation

Usually an angle of depression is less than or equal to 90°.

= Is a angle that is formed by a horizontal line and a line of sight to a point above the line.

Angle Of Depression

Usually an angle of depression is less than or equal to 90°.

= Is a angle formed by a horizontal line and a line of sight to a point below the line.

formula: tan y = opposite/adjacent
