Angle Calculator - Isosceles Triangles - Measure Angles and Side Lengths by entering 2 known values Enter Side Lengths and either top Angle or Base length to calculate all other side lengths, angles, triangle height and area. Find the degree measure of each angle shown below, and sketch the angle in standard position. Solution. a. The angle \(\alpha\) is one-fifth of a complete revolution, or ... When you ask your calculator to find an angle with a given sine by pressing 2ndSIN, it will give you only one of the many possible answers.
an angle in standard position is said to lie in the quadrant in which its terminal side lies. so if we thought of this angle as the rotation from this initial side to this terminal side, it would lie in the first quadrant. and we should also note there's an infinite number of angles that would also have this as its terminal side.
