Acute Angle Definition. An acute angle is an angle whose degree measure is greater than 0 but less than 90. In the above diagram angle 1 is seen smaller than the right angle marked by a square sign. Hence it is an acute angle. Similarly, the angle marked as 2 is called the complementary angle of angle 1.
Students will calculate the sine and cosine of both acute angles in a right triangle and explain why the sine of one acute angle is equal to the cosine of the complementary angle.irst to be completed will be a table with sides, side lengths, and sine and cosine values for the acute angles of five different triangles. Then, students will identify which values are the same and explain why the sine and cosine values of complementary angles are the same.
