Description
The purpose of geometry is to present geometrical concepts and patterns that are
impor
tant to the development of students’ thinking and problem

solving skills. The
students work with the body of geometry theorems, including theorems involving two
and three dimensions. The geometry skills and concepts developed in this discipline are
useful
to all students. Aside from learning these skills and concepts, students will
develop their ability to construct formal, logical arguments and proofs in geometric
settings and problems. Geometry AB meets the UC/CSU admission requirement.

n accordance with their individual capacity, students will grow in
the ability to:
• Apply algebraic skills developed in Algebra 1
• Complete basic po
stulates of Euclidean geometry and proofs of geometric theorems
• Use angles, parallel lines, congruent and similar triangles, rectilinear figures, circles
and arcs, and the Pythagorean Theorem
• Apply formulas for perimeters, areas, volumes, and surface a
reas of geometric figures
• Use geometric constructions and loci
• Use familiarity with geometric relationships to solve problems and draw conclusions.
• Apply right triangle trigonometry
• Solve standard geometric word problems
• Use geometric relationshi
ps accurately, including congruency and similarity
• Use basic mathematical vocabulary and terminology, standard notation and set of
symbols, common conventions for graphing and general features of effective
mathematical communication styles.

f
undefined terms, axioms, theorems, and inductive and deductive reasoning.
2.0
