Study Notes
Angles in Quadrilaterals
- The sum of the interior angles of a quadrilateral is 360 degrees.
Types of Quadrilaterals
- Common types of quadrilaterals include squares, rectangles, parallelograms, trapezoids, and rhombuses.
- A specific shape that is not classified as a quadrilateral is a pentagon (five sides).
Properties of Parallelograms
- In a parallelogram, opposite sides are equal in length and parallel.
- The sum of the opposite angles in a parallelogram equals 180 degrees.
- A quadrilateral is considered a parallelogram if it has one pair of opposite sides that are both equal and parallel.
Characteristics of Specific Quadrilaterals
- If a quadrilateral has one pair of opposite angles that are equal, it is most likely to be a parallelogram.
- In a trapezoid, the non-parallel sides are known as the legs, and they can be unequal or equal depending on the type of trapezoid.
Angles in Trapeziums
- The sum of the interior angles of a trapezium (or trapezoid) is also 360 degrees, similar to that of any quadrilateral.
