Classwork lesson/worksheets comprised of definitions and symbols for basic key geometric terms including: points, lines, segments, rays, parallel, perpendicular, intersecting, acute, right, obtuse, straight, complementary, supplementary. Sheets can serve as a useful reference sheet for students to hold onto and study. Sheets also include practice measuring angles and drawing angles. Some sheets are meant as homework (and are labeled so), but word document allows you to easily edit as you wish.
Though this is a 4th grade common core standard, I have used it a lot in 5th grade geometry as well.
