Solution for In a right triangle, which of the following is the definition of the tangent ratio? opposite adjacent adjacent opposite opposite hypotenuse.
The triangle is special because its side lengths are always in the ratio of 1: √3:2. Any triangle of the form 30-60-90 can be solved without applying long-step methods such as the Pythagorean Theorem and trigonometric functions. The easiest way to remember the ratio 1: √3: 2 is to memorize the numbers; "1, 2, 3". One precaution to using. Sine and cosine — a.k.a., sin (θ) and cos (θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin (θ) is the ratio of the opposite side to the hypotenuse, while cos (θ) is the ratio of the adjacent side to the hypotenuse. No matter the size of the triangle, the values of sin (θ) and cos.
The projection from X to P is called a parallel projection if all sets of parallel lines in the object are mapped to parallel lines on the drawing. Such a mapping is given by an affine transformation, which is of the form = f(X) = T + AX . where T is a fixed vector in the plane and A is a 3 x 2 constant matrix. Parallel projection has the further property that ratios are preserved.

The trigonometric functions are equal to ratios that relate certain side lengths of a right triangle. When solving for a missing side, the first step is to identify what sides and what angle are given, and then select the appropriate function to use to solve the problem. Evaluating a Trigonometric Function of a Right Triangle.
A trigonometric Table is a table of ratios of sides. In the Table, each value of sin θ represents the ratio of the opposite side to the hypotenuse -- in every right triangle with that acute angle. If angle θ is 28°, say, then in every right triangle with a 28° angle, its sides will be in the same ratio. We read in the Table,.
