# MATH130C: Geometry

Category
Credits 4 Lab/Practicum/Clinical Hours 0 Lecture Hours 4

Introduces the student to college-level Euclidean geometry, including definitions, postulates, and theorems. Topics include reasoning and proofs; parallel and perpendicular lines; triangles and congruence; quadrilaterals; circles; transformations; area; and analytic geometry. The course also introduces concepts in non-Euclidean geometry. The student will complete a required project. A graphing calculator, compass, protractor, and dynamic geometry software are required.

### Prerequisites

Students must pass all prerequisite courses with a grade of C or higher.

Learning Outcomes
• Use axioms, definitions, and given theorems to prove properties of geometry.
• Prove two triangles congruent under varying sets of hypotheses (the traditional SAS, SSS, ASA, AAS proofs).
• Use the inequality theorems for triangles to establish relationships between measures of sides and angles of triangles.
• Explain the difference between Euclidean and Non-Euclidean Geometries as related to the Parallel Postulate.
• Use symmetry and transformations to solve problems.
• Use logical reasoning in geometric proofs.
• Write analytic proofs using properties from algebra and congruence.
• Apply the properties of right triangles, including Pythagorean Theorem and similar right triangles, and trigonome-try.
• Apply the properties of circles to solve problems.
• Use geometric formulas to compute the area of plane figures.
