Geometry 1A, 1B

Geometry focuses on five critical areas: (1) using coordinate geometry to connect geometric and algebraic relationships to develop

concepts of proof; (2) applying the definition of congruence in terms of rigid transformations (translations, reflections, and rotations)

and applying congruence shortcuts for triangles to prove properties of triangles and quadrilaterals; (3) proving properties of circles

and using area and volume formulas in problem-solving situations; (4) applying the Pythagorean Theorem, right-triangle

trigonometry, and properties of similar triangles to calculate indirect measurements; and (5) using conditional probabilities to explore

events of chance. These concepts and associated skills are aligned with the Colorado Academic Standards for mathematics,

incorporating 21st century skills and postsecondary and workforce readiness competencies.
