Study Notes
What is a Parallelogram?
- A parallelogram is a geometric shape with four sides and two sets of parallel lines.
- Parallelograms are quadrilaterals, meaning they have four sides, four corners, and four angles.
- Real-world examples of parallelograms include notebooks, cell phones, and keyboards.
Characteristics of Parallelograms
- Parallelograms have either the same length for every side or two different side lengths (one length for each pair of parallel lines).
- They will never have more than two length values for the sides, or they wouldn't be considered a parallelogram.
Types of Parallelogram Shapes
- Squares are parallelograms with four sides of equal length and four right angles.
- Rectangles are parallelograms with two different side lengths and four right angles.
- Rhombuses are parallelograms with four sides of equal length, but no right angles.
- Rhomboids are parallelograms with two different side lengths and no right angles.
Properties of Parallelograms
- Quadrilateral: A parallelogram must have exactly four sides.
- Parallel sides: A parallelogram must have two sets of parallel lines opposite from one another.
- Bisecting lines: Lines drawn diagonally from each corner of a parallelogram will create bisecting lines.
- Equal side length: All parallelograms have at least one pair of sides of equal length.
- Congruent triangles: When a single line is drawn diagonally from one corner to another on a parallelogram, two congruent triangles are formed.
- Opposite but equal angles: Angles opposite from each other in a parallelogram will have the same measure.
- Opposite but equal lines: Parallelograms always have sides with the same length (congruent) as the side opposite from them.
Area of a Parallelogram
- The area of a parallelogram can be determined by multiplying the base by the height of the shape.
- The formula for the area of a parallelogram is A = B x H, where A is the area, B is the base length, and H is the height.
