NOTE
QUADRILATERALS
A quadrilateral is a polygon with four sides and four vertices. The sum of its interior angles is always 360 degrees. Quadrilaterals come in various forms and configurations, each with unique properties and characteristics. Examples include squares, rectangles, parallelograms, and trapezoids.
Types of quadrilateral
Quadrilaterals can be classified into several types based on their properties and characteristics. The following are some of the common types:
1. Square: A square is a quadrilateral with all four sides of equal length and all four angles of 90 degrees. It's a special type of rectangle and rhombus.
2. Rectangle: A rectangle is a quadrilateral with opposite sides equal and all angles of 90 degrees. Opposite sides are parallel and equal in length.
3. Parallelogram: A parallelogram is a quadrilateral with opposite sides parallel and equal in length. Opposite angles are also equal.
4. Rhombus: A rhombus is a quadrilateral with all four sides of equal length. Opposite angles are equal, but unlike a square, angles are not necessarily 90 degrees.
5. Trapezoid: A trapezoid is a quadrilateral with at least one pair of parallel sides. The parallel sides are called bases, and the non-parallel sides are called legs.
6. Kite: A kite is a quadrilateral with two distinct pairs of adjacent sides that are equal in length. It typically has one pair of opposite angles that are equal.
EVALUATION: 1. Draw out the following quadrilaterals.
CLASSWORK: As in evaluation
CONCLUSION: The teacher commends the students positively
