High School Geometry Test Prep is a free educational mobile app By Softschools.It helps students in grades HS practice the following standards HSG.CO.A.1,HSG.CO.A.2,HSG.CO.A.3.
1. HSG.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.
2. HSG.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)..
3. HSG.CO.A.3 : Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself..
