A 2D shape or two-dimensional shape is a flat figure that has two dimensions—length and width. Learn examples, formulas, properties of 2D shapes and much more!
A parallelogram is defined as a quadrilateral in which both pairs of opposite sides are parallel and equal. Observe the following figure which shows the three types of parallelograms: Properties of a Parallelogram. There are some basic properties that help us to identify a parallelogram.
There is an endless variety of 2D geometric shapes, but we’ll take a look at the names and properties of some of the most common, starting with the basic shapes and moving on to more complex ones. But first, what exactly is a 2D shape? What are 2D shapes? Two-dimensional shapes are figures with only two dimensions: width and length.
Parallelograms are quadrilaterals with opposite sides being parallel to each other. Parallelograms have other unique properties. Properties of a Parallelogram. ★ Two pairs of opposite congruent sides. Side. AB AB and Side. DC DC are congruent. Side. AD AD and Side. BC BC are congruent. ★ Two pairs of opposite congruent angles. Angle. A A and Angle.
A parallelogram is defined as a two-dimensional geometric shape and possesses two sets of parallel sides with equal lengths. What is a Parallelogram Shape? A quadrilateral, or four-sided polygon, is one kind of parallelogram. However, not all quadrilaterals are parallelograms.
A parallelogram is a quadrilateral in which the opposite sides are parallel (Figure 3.1.3 ). To discover its properties, we will draw a diagonal, a line connecting the opposite vertices of the parallelogram. In Figure 4, AC is a diagonal of parallelogram ABCD. We will now prove ΔABC ≅ ΔCDA.
Example: A parallelogram has a base of 12 cm and a side length of 6 cm, what is its Perimeter? Perimeter = 2 × (12 cm + 6 cm) = 2 × 18 cm = 36 cm Diagonals of a Parallelogram
