# Q3, W3: Geometry (January 21-25)

Teacher Kristin Andreason Geometry Honors 8 Three Unit 5: Quadrilaterals and Coordinate Geometry
Standard(s) Taught

MAFS.912.G-CO.3.11:  Prove theorems about parallelograms to solve problems.  Theorems include:  opposite sides are congruent, opposite angles are congruent, the diagonals of a parallelogram bisect each other, and conversely, rectangles are parallelograms with congruent diagonals.

MAFS.912.G-GPE.2.4:  Use coordinates to prove simple geometric theorems algebraically. Choose appropriate formula to identify the geometric figure and its properties.  Prove or disprove that a figure defined by given points in the coordinate plane is a triangle, rectangle, kite, rhombus, trapezoid, square, etc.

Learning Targets and Learning Criteria
• Students will learn the properties of parallelograms and understand the differences between types of parallelograms such as rhombus, rectangle, and square.
• Students will be able to find missing side lengths or angle measures of parallelograms based on the properties of the different types of parallelograms.
• Students will apply theorems, postulates, or definitions to prove theorems about parallelograms.
Classroom Activities

Tuesday and Wednesday:

• Students will complete a graphic organizer on quadrilaterals.
• Students will work in pairs to complete the Square/Rhombi Partner Activity.
• Students will do IXL N.10.

Thursday/Friday:

• We will work through a review packet on Quadrilaterals to review for a summative.
Assignments Due
• Square/Rhombi Partner Activity due on January 23.
• IXL N.10 due by Monday, January28.
