Geometry Unit 7
Quadrilaterals
5 Instructional Days - 3rd 6 Weeks
Hyperlinks are for content teachers
Big Idea:
Develop properties of quadrilaterals using angles, sides, and diagonals
Student Expectations:
Priority TEKS
G.5(A) [Readiness] investigate patterns to make conjectures about geometric relationships, including angles formed by parallel lines cut by a transversal, criteria required for triangle congruence, special segments of triangles, diagonals of quadrilaterals, interior and exterior angles of polygons, and special segments and angles of circles choosing from a variety of tools
Focus TEKS
G.6(D) [Supporting] verify theorems about the relationships in triangles, including proof of the Pythagorean Theorem, the sum of interior angles, base angles of isosceles triangles, midsegments, and medians, and apply these relationships to solve problems
G.6(E) [Supporting] prove a quadrilateral is a parallelogram, rectangle, square, or rhombus using opposite sides, opposite angles, or diagonals and apply these relationships to solve problems

Student Learning Targets:
- I will prove and use the Triangle Mid-segment Theorem.
- I will develop and prove properties of trapezoids, parallelograms, rectangles. Rhombuses, and squares.
- I will develop, prove, and apply criteria for showing that a quadrilateral is a parallelogram.
- I will develop, probe and apply criteria for showing that a quadrilateral is a rectangle.
- I will develop, probe and apply criteria for showing that a quadrilateral is a rhombus.
- I will develop, probe and apply criteria for showing that a quadrilateral is a square.
Essential Questions:
- How does the nature of a particular quadrilateral affect the angle, side, and diagonal relationships within the quadrilateral?
