Euclidean geometry course is required of all students receiving an Alabama High School Diploma.
School systems may offer Geometry and Geometry A and Geometry B.
Content standards 1, 3, 4, 5, 6, 7,
8, 9, 10, 11, 12, 13, 14, 15, 16, 26, 30, 31, 32, 33, and 34 must be taught in the Geometry A course.
Content standards 2, 12, 17, 18, 19, 20, 21, 22, 23, 24, 25, 27, 28, 29, 35, 36, 37, 38, 39, 40, 41, 42, and
43 must be taught in the Geometry B course.
Students will:
GEOMETRY
Congruence
Experiment with transformations in the plane.
1.
Know precise definitions of angle, circle, perpendicular line, parallel line, and line segment based
on the undefined notions of point, line, distance along a line, and distance around a circular arc.
[G-CO1]
2.
Represent transformations in the plane using, e.g., transparencies and geometry software; describe
transformations as functions that take points in the plane as inputs and give other points as outputs.
Compare transformations that preserve distance and angle to those that do not (e.g., translation
versus horizontal stretch).
[G-CO2]
3.
Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and
reflections that carry it onto itself.
[G-CO3]
4.
Develop definitions of rotations, reflections, and translations in terms of angles, circles,
perpendicular lines, parallel lines, and line segments.
[G-CO4]
5.
Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure
using, e.g., graph paper, tracing paper, or geometry software.
Specify a sequence of
transformations that will carry a given figure onto another.
