Properties of quadrilaterals and the interior and exterior angles of quadrilaterals
What you need to learn in this topic
- Describe the geometric properties of various types of quadrilaterals. Hence classify quadrilaterals based on the geometric properties.
- Make and verify the conjectures about (i) the sum of interior angles of a quadrilateral, (ii) the sum of interior angle and adjacent exterior angle of a quadrilateral, and (iii) the relationship between the opposite angles in a parallelogram.
- Solve problems involving quadrilaterals.
- Solve problems involving the combinations of triangles and quadrilaterals.
