STEPS Identify the type of quadrilateral Identify the property that you need to use Set up the equation using your property and the given information. Additional points will go as Extra Credit on last Thursday’s Quiz!ĥ Using Algebra with Properties of Quadrilaterals You will earn 1 point for each accurate property and 1 additional point for each accurate property that no one else has identified. A property must ALWAYS be true of the shape, so move them around to be sure your property stays true. Use the guiding questions under each as prompts. Use the GeoGebra Workbook to complete your checklist of the properties of quadrilaterals. A (1, 3) B (2, 1) C (6, 3) D (5, 5)Ī diagonal is a line segment that connects non-consecutive vertices.
