# Discovering the Properties of Quadrilaterals

To understand the properties of a quadrilateral, students begin by examining the ... (more)

To understand the properties of a quadrilateral, students begin by examining the relationship between angles in a triangle. Using several different types of triangles, students cut off two angles and rearrange them to show that the sum of all three angles is equal to 180 degrees. Mr. Hassoun then challenges students to do the same with quadrilaterals, asking them to form a conjecture about the sum of the four angles in a quadrilateral. Students continue their exploration of quadrilaterals by drawing and measuring the diagonals. Using several quadrilaterals, students discover properties relating to the length and angle relationships of the diagonals. Having students physically manipulate the properties and formulate their own conjectures helps them to remember the different properties and form a deeper understanding of the patterns in geometry.
