Projection Geometry Diagram - Vertical and Horizontal Components Explained #160715 (License: Personal Use)

This hand-drawn diagram depicts a foundational concept in analytic geometry: the orthogonal projection of two points (α and β) onto a horizontal axis. Dashed lines indicate vertical projections (αᵛ, βᵛ) intersecting the baseline at αʰ and βʰ, while solid lines show oblique connections to a common origin O and secondary point O′. The central point r serves as the foot of the perpendicular from βᵛ to the baseline.

Used in mathematics education, particularly in trigonometry, vector analysis, or coordinate geometry lessons; supports user intent to understand projection principles, solve related problems, or visualize spatial relationships in 2D.
