Answer the questions below the diagram using your understanding of the learning targets, and GeoGebra tools.

GeoBasics: I can explain and use the basic terminology of geometry

  • GeoBasics1.1: I know the four, undefined terms: point, line,plane, solid and can use them as the basis of geometric proofs (G.PL.1)(G.PL.3) (G.LP.1)
  • GeoBasics1.2: I explain and can use the following terms: segment, ray, intersection, parallel and perpendicular lines, vertical and adjacent angles, interior and exterior angles, complementary and supplementary angles, angle and segment bisectors, right angle, transversal, equidistant, congruent (G.PL.3)

GeoCircles: I can explain and use the basic terminology of circular geometry

  • GeoCircles1.1: I can identify, explain and use and use the following parts of a circle: radius, diameter, circumference, area (G.Cl.1)
  • GeoCircles1.2: I can identify, define and use the following constructions on a circle: arc length, chord, secant, tangent, central, inscribed and circumscribed angles, sector (G.Cl.1) (G.Cl.2)
