What you’ll find in this zyBook:

More action with less text

  • Exceptionally interactive material on Euclidean and non-Euclidean geometries
  • Hundreds of auto-graded activities such as question sets, animations, and challenge activities
  • An interactive embedded GeoGebra applet for doing geometry constructions
  • Interactive two-column proofs for Euclidean and non-Euclidean geometries

The zyBooks Approach

Less text doesn’t mean less learning

This material provides an interactive approach to geometry. This release covers Euclidean plane geometry including two-column proofs for theorems on angles, triangles, quadrilaterals, and circles. The release also covers basic analytic and non-Euclidean geometries, and reviews basic trigonometry. The non-Euclidean geometry chapter covers axiomatic proofs. Constructions are included in the zyBook using an interactive GeoGebra tool.
