Please help! Medal and fan for best answer :) How do similar right triangles lead to the definitions of the trigonometric ratios?

    I don't really understand the question. Usually the answers are in my notes and this is what my notes say The term trigonometry comes from a Greek word meaning “triangle measuring.” The sine of an angle within a right triangle is found by dividing the length of the opposite side by the length of the hypotenuse. The cosine of an angle within a right triangle is found by dividing the length of the adjacent side by the length of the hypotenuse. The tangent of an angle within a right triangle is found by dividing the length of the opposite side by the length of the adjacent side.

    forget the notes , just try to draw to similar right triangles by scale and pencil then choose any and other than 90 degree name it \('x'\). then find the ratio of side opposite to \('x'\) and hypotenuse in both triangles u will find the ratio is constant and that ratio is known as \(\sin 'x'\) similarly all other trignometric ratios will be equal

    So they relate because when you find the sine, cosine, and tangent of the similar triangles they will all be equal?

    yes if the angles will be equal
