If you’re diving into Common Core Algebra 2 , you’ve likely encountered a shift in how you measure angles. Degrees are out (well, not entirely), and radians are in. Many students find this transition confusing at first, but radians are actually a more natural, universal way to measure angles—especially in advanced math, physics, and engineering.
