Expectations

  • G.GSR.4.1

    Use the undefined notions of point, line, line segment, plane, distance along a line segment, and distance around a circular arc to develop and use precise definitions and symbolic notations to prove theorems and solve geometric problems.

  • G.GSR.4.2

    Classify quadrilaterals in the coordinate plane by proving simple geometric theorems algebraically.

  • G.GSR.4.3

    Make formal geometric constructions with a variety of tools and methods.

  • G.GSR.4.4

    Prove and apply theorems about lines and angles to solve problems.

  • G.GSR.4.5

    Use geometric reasoning to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.
