Jan 26, 2016 - Constructions segue into Topic B, Unknown Angles, which consists of unknown angle problems and proofs.  These exercises consolidate students’ prior body of geometric facts and prime students’...

Jan 26, 2016 - In Topic D, Proving Properties of Geometric Figures, students use what they have learned in Topics A through C to prove properties—those that have been accepted as true and those that are new—of...

Jan 26, 2016 - Topic F is a review that highlights how geometric assumptions underpin the facts established thereafter.

Jan 26, 2016 - Students solve polynomial, rational, and radical equations, and apply these types of equations to real-world situations.  They examine the conditions under which an extraneous solution is introduced...

Jan 26, 2016 - The challenge of programming robot motion along segments parallel or perpendicular to a given segment leads to an analysis of slopes of parallel and perpendicular lines.  Students write equations for...

Jan 26, 2016 - Students find midpoints of segments and points that divide segments into 3 or more equal and proportional parts and extend this concept prove classical results in geometry.  Students are introduced...

Jan 26, 2016 - Students study and prove the properties of dilations.

Jan 26, 2016 - The focus in Topic D is similarity within right triangles.  Students examine how an altitude drawn from the vertex of a right triangle to the hypotenuse creates two similar sub-triangles.  Students...

Jan 26, 2016 -  Students begin their work with 3-dimensions by first developing a stronger sense of area in two dimensions.  They find approximated areas of curved figures by “squeezing” them between inscribed and...

Jan 26, 2016 - Topic A leads students first to Thales' theorem (an angle drawn from a diameter of a circle to a point on the circle is sure to be a right angle), then to possible converses of Thales' theorem, and...

Jan 26, 2016 - In Topic C, students explore geometric relations in diagrams of two secant lines, or a secant and tangent line (possibly even two tangent lines), meeting a point inside or outside of a circle.  They...
