Recall that angles in standard position start from the positive x-axis and rotate counterclockwise.
Identify the range of angles for each quadrant: Quadrant I is from 0° to 90°, Quadrant II is from 90° to 180°, Quadrant III is from 180° to 270°, and Quadrant IV is from 270° to 360°.
Given the angle is 100°, determine which quadrant this angle falls into by comparing it to the ranges above.
Since 100° is greater than 90° but less than 180°, it lies in Quadrant II.
Therefore, the terminal side of the 100° angle in standard position is in Quadrant II.
