Noncredit Glendale Community College May 2014 COURSE OUTLINE Adult Basic and Secondary Education 025 Geometry 1A I. Catalog Statement Adult Basic and Secondary Education 025 is the first half of a one -year high school level geometry course. In this course the notion of two-dimensional shapes as part of the Euclidian Plane and exploration of transformations of this plane as a way to determine whether two shapes are congruent are formalized. Students use transformations to prove geometric theorems. This course is designed to meet the needs of students who wish to begin their study of geometry and to earn high school credit in math. Units: 0.0 Total Laboratory Hours: 100.0 Total Faculty Contact Hours: 100 Recommended preparation: ESL 040 or equivalent, ABSE 024 or equivalent. Note: This is a self-paced course in an open-entry, open-exit lab environment. Successful completion of this course is worth 5 credits (.5 unit) towards a high school diploma. II. Course Entry Expectations Skills Level Ranges: Reading: 5; Writing: 4; Listening/Speaking: 4; and Math: 4. III. Course Exit Standards Upon successful completion of the required coursework, the student will be able to: 1. make a variety of formal geometric constructions using a variety of tools; 2. experiment with transformations in the plane; 3. understand congruence in terms of rigid motions; 4. explain triangle congruence in terms of rigid motion; 5. prove theorems about lines and angles, triangles, and parallelograms.

Student Learning Outcome Upon Successful completion of the required coursework, the student will be able to: 1. make formal geometric constructions with a variety of tools and methods: copying a segment, copying an angle, bisections of a segment or of an angle, construction of the perpendicular bisector of a line segment, and constructing a line parallel to a given line through a point not on the line; 2. use rigid motion to map corresponding parts of congruent triangles onto each other and use the criteria for triangle congruence (ASA, SAS, and SSS) to prove triangle congruence; 3. prove theorems about lines and angles: vertical angles are congruent; when a transversal crosses parallel lines, alternate interior angles are congruent and corresponding angles are congruent; 4. prove theorems about triangles: measures of interior angles of a triangle sum to 180; base angles of isosceles triangles are congruent; the segment joining midpoints of two sides of a triangle is parallel to the third side and half the length; the medians of a triangle meet at a point; 5. verify experimentally that in a triangle, angles opposite longer sides are larger, sides opposite larger angles are longer, and the sum of any two sides lengths is greater than the remaining side length.
