Study Notes
Angles in a Parallelogram
- If one angle measures 120 degrees, the adjacent angle's measure equals 60 degrees, derived from the property that adjacent angles in a parallelogram are supplementary.
- The sum of all interior angles in a parallelogram is 360 degrees, consistent with the formula for the sum of interior angles in any quadrilateral.
Properties of Sides in a Parallelogram
- Opposite sides in a parallelogram are equal in length, indicating that the opposite sides are congruent, which is a fundamental property of parallelograms.
Types of Quadrilaterals
- A quadrilateral that has both pairs of opposite sides parallel and equal in length is called a rectangle, which is a specific type of parallelogram.
