Description
This visual dictionary is an excellent resource for the first week of high school geometry. Includes an introduction to the following concepts:
- Naming points, lines, segments, rays, and angles
- Distinguishing between acute, right, and obtuse angles
- Key definitions of quadrilaterals (parallelogram, rectangle, rhombus, square, trapezoid)
- Parallel and perpendicular segments/lines.
- Transformation definitions - translation, reflection, rotation (distinguishing between counterclockwise and clockwise)
- Memory aids for horizontal vs. vertical lines

Standards
to see state-specific standards (only available in the US).
CCSSHSG-CO.A.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.
CCSSHSG-CO.A.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).
CCSSHSG-CO.A.4
Develop definitions of rotations, reflections, and translations in terms of angles, circles, perpendicular lines, parallel lines, and line segments.
