SOHCAHTOA TOA CAH SOH The three trigonometric ratios for right angled triangles are considered here. Click on a box to select a ratio.
SOHCAHTOA SOH On the unit circle sin is observed sin 1 Back to menu
SOHCAHTOA sin 1 SOH Now take a similar triangle
SOHCAHTOA Opp Hyp By similar triangles SOH = sin = sin 1
SOHCAHTOA cos 1 CAH On the unit circle cos is observed Back to menu
SOHCAHTOA cos 1 CAH Now take a similar triangle
SOHCAHTOA Adj Hyp By similar triangles CAH = cos = cos 1
SOHCAHTOA TOA On the unit circle tan is observed tan 1 1 Back to menu
SOHCAHTOA TOA tan 1 Now take a similar triangle
SOHCAHTOA By similar triangles TOA Adj Opp tan 1 tan = =

4.1 – Right Triangle Trigonometry. Sin Ɵ = opp hyp.
Trigonometry Review of Pythagorean Theorem Sine, Cosine, & Tangent Functions Laws of Cosines & Sines.
Find the missing measures. Write all answers in radical form. 60° 30° 10 y z Warm – up 3 45 y 60 30 x 45
1 Objectives Define and apply sine, cosine, and tangent in right triangles.
QUADRANT I THE UNIT CIRCLE. REMEMBER Find the length of the missing side: x y x y x y Aim: Use the unit circle in order to find the exact value.
Right Triangle Trigonometry. Objectives Find trigonometric ratios using right triangles. Use trigonometric ratios to find angle measures in right triangles.
Trigonometry can be used for two things: 1.Using 1 side and 1 angle to work out another side, or 2.Using 2 sides to work out an angle.
Trigonometric Ratios Consider the triangle given below. 1.The box in the bottom right corner tells us that this is a right triangle. 2.The acute angle.
TRIGONOMETRY Find trigonometric ratios using right triangles Solve problems using trigonometric ratios Sextant.
7.3 Special Angles (30 & 60 ). Equilateral Triangle 60 angles w/ sides = 1 Drop Perpendicular Bisector to form 1 60 60 30.
7.3 Special Angles (45 & Quadrantal)
Presents Let’s Investigate Extension The Tangent ratio The Sine ratio The Cosine ratio The three ratios.
Six Example with choice
