Trades Geometry

At 6:42 AM the slab is cold, coffee steams on the foundation wall, and the foreman says, "Get it level."

Trades Geometry is not an attempt to make you into a mathematician. It is the geometry that keeps a building straight, a pipe running clean, a roof shedding water, and a job profitable, taught through the situations where you actually need it.

A rectangle can rack. A triangle cannot. Every chapter starts on the job site:

- Lines and levels: benchmarks, plumb, and working from control lines

- Triangles: 3-4-5, 6-8-10, and proving a corner square

- Circles and arcs: wraps, partial arcs, and round runs when you cannot reach the center

- Area and material estimation: turning odd shapes into provable boxes

- Volume: concrete, capacity, gallons, and yards

- Framing and roof pitch: rise, run, rafters, hips, and valleys

- Geometric heritage: how builders checked their work before lasers

- The digital blueprint: CAD and precision layouts

For apprentices, tradespeople, homeschool students, and anyone who was never shown how the math in school connects to real work.
