Course Plan
Date: August 1, 2011- 2013
MAT 120, Geometry and Trigonometry
2 lecture hours and 2 lab hours for 3 semester hours credit
Course Description: This course introduces the concepts of plane trigonometry and geometry with
emphasis on applications to problem solving. Topics include the basic definitions and properties of
plane and solid geometry, area and volume, right triangle trigonometry and oblique triangles. Upon
completion, students should be able to solve applied problems both independently and collaboratively
using technology.
Course Objectives:
 Students will be able to evaluate and manipulate geometry formulas.
 Students will be able to sketch graphs of basic functions and create new functions using
transformations, symmetry, and/or adding, subtracting, multiplying, dividing, or composing
functions.
 Students will be able to solve problems involving ratio and proportions.
 Students will be able to define geometric terms and apply properties of plane geometry.
 Students will be able to find volume and surface area of solid geometric figures.
 Students will be able to solve right triangles using right triangle trigonometry.
 Students will be able to solve applied problems using right triangle trigonometry.
Student Learning Outcomes:
 Model and solve real-world applications mathematically
 Perform mathematical calculations appropriate for the discipline of study

Grading Policy: Grading policies will be included in the syllabus and distributed to all students at the
beginning of each semester. In all curriculum math courses the grading scale is the same: A = 100-90, B =
89-80, C = 79-70, D = 69-60, F = 59-0.
Disability Services: Alamance Community College is committed to providing equal educational
opportunities for students with documented disabilities. Students who require disability services or
reasonable accommodations must identify themselves as having a disability and provide current
diagnostic documentation to the Disability Services Office located in the Gee Building, Room 128. All
information is confidential. Please contact Monica Isbell, Coordinator of Special Needs & Counseling
Services for more information at 336-506-4130 or email at isbellm@alamancecc.edu.
Student Access to Faculty: Instructors will provide students with a written syllabus that includes their
name, office number, telephone number, e-mail address and office hours.
Attendance Policy: The standard ACC attendance policy will be followed (see the ACC Student
Handbook for details.) The attendance policy may be modified by departments as approved by the
Associate Dean. The specific attendance policy for this course will be provided in the syllabus.
Academic Integrity: Students should review the Student Code of Conduct section of the Student
Handbook.
Course Evaluation: This course will be regularly evaluated in accordance with college policy.
