# Help writing proofs for geometry

What is a proof? ## Worked examples

Proving a Quadrilateral is a Parallelogram Geometry Proof This video geometry lesson proves two parallelogram theorems using the two column proof. If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram.

If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram. If both pairs of opposite angles of a quadrilateral are congruent, then the quadrilateral is a parallelogram and If one pair of opposite sides of a quadrilateral is both congruent and parallel, then the quadrilateral is a parallelogram to solve problems.

Special Parallelograms - Rhombus and Rectangle Proofs This video uses the two column method to prove two theorems. The diagonals of a rectangle are congruent.

Please submit your feedback or enquiries via our Feedback page.Apr 28,  · In this lesson, students learn to set up and complete two-column Geometry proofs using the properties of equality as well as postulates and definitions from Geometry. Geometry is shapes and angles, not writing out two-column and paragraph proofs.

You're half right. Geometry is about shapes and angles (and some other stuff as well), but the point of geometry is to accumulate knowledge about shapes and angles. Videos, examples, solutions, worksheets, games and activities to help Geometry students learn how to use two column proofs.

A two-column proof consists of a list of statements, and the reasons why those statements are true. For example, when our group discussion, ranged from the geometry help homework proofs parasession on lexical and syntactic skills.
