Polygons and Quadrilaterals: Definitions and Classifications
Polygons are closed figures formed by straight lines. Quadrilaterals are polygons with four sides. Polygons can be classified based on the number of sides they have, while quadrilaterals can be classified based on the length of their sides and the angles between them.
Examples of polygons include triangles (3 sides), squares (4 sides), pentagons (5 sides), and hexagons (6 sides). Examples of quadrilaterals include squares (4 equal sides, 4 right angles), rectangles (4 equal sides, 2 pairs of parallel sides), parallelograms (4 sides, 2 pairs of parallel sides), and trapezoids (1 pair of parallel sides).
Properties of polygons include the sum of the interior angles being (n-2) – 180 degrees, where n is the number of sides. Properties of quadrilaterals include opposite sides being parallel and opposite angles being equal.
Area and Perimeter of Polygons and Quadrilaterals
The area of a polygon is the amount of space it encloses. The perimeter of a polygon is the distance around its edges.
The area of a rectangle is calculated as length – width. The perimeter of a rectangle is calculated as 2 – (length + width).
The area of a triangle is calculated as 0.5 – base – height. The perimeter of a triangle is calculated as the sum of the lengths of its three sides.
Properties of Specific Quadrilaterals: Polygons And Quadrilaterals Unit Test
Squares
- All sides are equal.
- All angles are right angles (90 degrees).
- Diagonals are equal and bisect each other.
Rectangles, Polygons and quadrilaterals unit test
- Opposite sides are equal.
- Opposite angles are equal.
- Diagonals are equal.
Parallelograms
- Opposite sides are parallel.
- Opposite angles are equal.
Trapezoids
- One pair of opposite sides is parallel.
- Non-parallel sides are called legs.
- Bases are the parallel sides.
Transformations of Polygons and Quadrilaterals
Transformations are operations that can be applied to polygons and quadrilaterals to change their position, size, or shape.
Translations
Translations move a polygon from one point to another without changing its size or shape.
Rotations
Rotations turn a polygon around a fixed point.
Reflections
Reflections flip a polygon over a line.
Applications of Polygons and Quadrilaterals
