 Student Outcomes Students learn to construct an equilateral triangle. Students communicate mathematic ideas effectively and efficiently.

 Student Outcomes Students review formerly learned geometry facts and practice citing the geometric justifications in anticipation of unknown angle proofs.

 Student Outcomes Students review formerly learned geometry facts and practice citing the geometric justifications in anticipation of unknown angle proofs.

 Student Outcomes Students apply the equilateral triangle construction to more challenging problems. Students communicate mathematical concepts clearly and concisely.

 Student Outcomes Students learn how to bisect an angle as well as how to copy an angle.

 Student Outcome Students review formerly learned geometry facts and practice citing the geometric justifications regarding angles in a triangle in anticipation of unknown angle proofs.

 Student Outcome Students learn to construct a perpendicular bisector and about the relationship between symmetry with respect to a line and a perpendicular bisector.

 Student Outcome Students become familiar with vocabulary regarding two points of concurrencies and understand why the points are concurrent.

 Student Outcomes Students discover the gaps in specificity regarding their understanding of transformations. Students identify the parameters they need to complete any rigid motion.

 Student Outcome Students write unknown angle proofs, which does not require any new geometric facts. Rather, writing proofs requires students to string together facts they already know to reveal...

 Objective: Find and describe flat triangles, squares, rectangles, hexagons, and circles using informal language without naming.

 Student Outcomes Students manipulate rotations by each parameter—center of rotation, angle of rotation, and a point under the rotation.

 Student Outcomes Students learn why any two triangles that satisfy the SAS congruence criterion must be congruent.

 Student Outcome Students write unknown angle proofs involving auxiliary lines.

 Student Outcomes Students write unknown angle proofs involving known facts.

 Student Outcomes Students complete proofs that incorporate properties of parallelograms.

 Objective: Classify shapes based on defining attributes using examples, variants, and nonexamples.

 Student Outcomes Given a physical situation (e.g., a room of a certain shape and dimensions, with objects at certain positions and a robot moving across the room), students impose a coordinate system...

 Student Outcomes Students learn the precise definition of a reflection. Students construct the line of reflection of a figure and its reflected image. Students construct the image of a figure when...

 Student Outcomes Students learn the relationship between a reflection and a rotation. Students examine rotational symmetry within an individual figure.

 Objective: Describe twodimensional shapes based on attributes.

 Student Outcome Students learn the precise definition of a translation and perform a translation by construction.

 Student Outcomes Students examine two different proof techniques via a familiar theorem. Students complete proofs involving properties of an isosceles triangle.

 In the last lesson, students learned about the triangle side splitter theorem, which is now used to prove the dilation theorem. In Grade 8 students learned about the fundamental theorem of...
