How does the tangent of an acute angle in a right triangle change as the angle measure increases?

As an angle increases, the length of its opposite leg increases. Therefore, \begin{align*}\frac{opposite \ leg}{adjacent \ leg}\end{align*} increases and thus the value of the tangent ratio increases.

What is the tangent of an acute angle in a right triangle?

The ratio called tangent (tan) of an acute angle in a right angled triangle is defined as the ration between the side opposite the angle and the side adjacent to the angle .

What is the relationship between the two acute angles in a right triangle?

Two acute angles of a right-angled triangle are “Complementary Angles.”

Is it possible for the sine of an acute angle in a right triangle to be equal to its cosine?

Since the measures of these acute angles of a right triangle add to 90º, we know these acute angles are complementary. ∠A is the complement of ∠B, and ∠B is the complement of ∠A. The sine of any acute angle is equal to the cosine of its complement.

How do you find the tangent of a right triangle?

In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). In a formula, it is written simply as ‘tan’.

Are the two acute angles in a right triangle the same?

Explanation: A right triangle can, and must, have exactly two acute angles. Thus, both of the remaining two angles must have a measure less than 90∘ and therefore must be acute.

What does the tangent ratio compare?

The tangent ratio is a comparison between the two sides of a right triangle that are not the hypotenuse. If two different sized triangles have an angle that is congruent, and not the right angle, then the quotient of the lengths of the two non-hypotenuse sides will always give you the same value.

How do you calculate sine of an angle?

In any right angled triangle, for any angle:

1. The sine of the angle = the length of the opposite side. the length of the hypotenuse.
2. The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
3. The tangent of the angle = the length of the opposite side. the length of the adjacent side.
