One-Point Perspective• All lines in the depth
project to one point (the vanishing point).
• #5 - Copy this one-point perspective sketch onto your activity. Label the front, top, and right side.

Two-Point Perspective
• In two-point perspective, the width lines converge on one vanishing point (VP1), and the depth lines converge on the other vanishing point (VP2).
• #6-Copy this two-point perspective onto your activity sheet. Label the top, front, and side.
