Angles & Radians
By the end you will convert degrees ↔ radians without a calculator for the common landmarks (0°, 30°, 45°, 60°, 90°, 180°), explain why robotics libraries prefer radians, and write a tiny “unit contract” for your future arm code.
An angle measures how much you turn. Two common units:
