A trigonometric ratio is a ratio of the measures of two sides of a right triangle. One trigonometric ratio is the tangent ratio. The short form for the tangent ratio of angle A is tan A. Example 1: Write each trigonometric ratio. tan A. tan B. Example 2: Calculate tan 25( to four decimal places. Draw a triangle to represent tan( = 5/4.

In other words, if two right triangles have congruent hypotenuses and one pair of congruent angles (in addition to the congruent right angles), the triangles are guaranteed to be congruent. HA Theorem: If the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and corresponding acute angle of another right ...

Then, since the sum of the angles of a triangle is 180°, the other two angles add to 180° − x. Which is fine. This argues that a triangle may have at least one angle that is obtuse. Now suppose the triangle has two right angles, two obtuse angles, or one right and one obtuse.
