How to reflect a triangle over the x axis

The video tutorial explains how to reflect a figure over the X axis. It introduces the concept of reflection as flipping a figure over an axis of symmetry. The tutorial provides a rule for reflecting points: change the sign of the Y coordinate while keeping the X coordinate unchanged. The instructor demonstrates this rule using points A, B, and C, transforming them into A prime, B prime, and C prime. Finally, the transformed points are graphed to verify the reflection, ensuring they form a mirror image across the X axis.
