Understanding Angles in Standard Position & Quadrant Angles 📐

Lesson#2 <br />What is Angle in Standard Position ? <br />An angle is said to be in standard position if its vertex lies at the origin and its initial side along the positive −. <br />Math.Ex.9.2, Part2(9.2) <br />What is Quadrantle Angle ? <br />• For an angle in standard position, if terminal side lies on any axis, then it will be called quadrantle angle. <br />0° , ±90° , ±180° ,±360° . . . are all quadrantle angles. <br />• (90°) or /2 where ∈ℤ is generator of all quadrantle angles. <br />• For an angle in standard position, if terminal side lies in any of the quadrant, then it will be called non− quadrantle angle. <br />Chapter No. 9 <br />Fundamentals of Trigonometry <br />Exercise No. 9.2 <br />mathematics <br />part 1
