Solution Angles And Their Measure Studypool Initially, trigonometry dealt with relationships among the sides and angles as derived from the greek language, the word trigonometry means “measurement oftriangles.” solution: angles and their measure studypool. Coterminal angles θ are of the form θ = α 2π ⋅ k, for some integer k. to make the arithmetic a bit easier, we note that 2π = 12π 6, thus when k = 1, we get θ = π 6 12π 6 = 13π 6. substituting k = − 1 gives θ = π 6 − 12π 6 = − 11π 6 and when we let k = 2, we get θ = π 6 24π 6 = 25π 6. Recall that two acute angles are called complementary angles if their measures add to \(90^{\circ}\). two angles, either a pair of right angles or one acute angle and one obtuse angle, are called supplementary angles if their measures add to \(180^{\circ}\). in the diagram below, the angles \(\alpha\) and \(\beta\) are supplementary angles. Standard position. an angle fits a u000bcoordinate system in which the origin u000bis the vertex and the initial side u000bcoincides with the positive x axis. positive angles. are generated by counterclockwise rotation. negative angles. clockwise rotation. coterminal. angles that have the same initial and terminal sides. denoted.

Trigonometry is the branch of mathematics that the relations between the sides and angles of trianglesstudies . the word “trigonometry” comes from the greek trigōnon (triangle) and metron (measure.) it was first studied by the babylonians, greeks, and egyptians, and used in surveying, navigation, and astronomy. trigonometry is a. Example 1. draw each of the following angles in standard position: a. 45° b. 225° c. 90° d. 270° e. − 135 ° f. 405°. we refer to angles with the same initial and terminal sides, like examples a. and f., as coterminal angles. an angle of x ° is coterminal with angles of x ° k ⋅ 360 ° where k is an integer. example 2.
