Parallelogram

Et parallellogram er en firkant, altså en figur innenfor geometri, med fire sider. Alle disse deler den egenskapen at summen av de fire vinklene alltid er lik 3grader. Parallelogram (polygon). Sidekantene er parvis like lange.

Motstående vinkler er parvis like store.

Diagonalene i et parallellogram deler hverandre på midten. Alle parallellogram er også trapes. In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The congruence of opposite sides and opposite angles is a direct . One special kind of polygons is called a parallelogram.

It is a quadrilateral where both pairs of opposite sides are parallel. Opposite angels are congruent (D = B). An since a square is a degenerate case of a rectangle, both squares and rectangles are special types of parallelograms.

Understand why the formula for the area of a parallelogram is base times height, just like the formula for the. Sal finds the height of a parallelogram when given the area and base length. A parallelogram is a quadrilateral whose opposite sides are parallel. The fundamental definition of a . Geometry Teachers Never Spend Time Trying to Find Materials for Your Lessons Again!

Or: Both pairs of opposite sides are congruent. A quadrilateral is a parallelogram if: Both pairs of opposite sides are parallel. If they are congruent, they must also be parallel. Or: One pair of opposite sides are congruent and parallel. Then, the other pair must also be parallel.

The area of a parallelograparallelogram. To find the area of a parallelogram , just multiply the base length (b) times the height (h):. Area = length x width = b x h. The diagonals are perpendicular bisectors of each other.

The rectangle has the following properties: All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite sides are congruent, and diagonals bisect each other). All angles are right angles by definition.

In this lesson, you’ll learn that there are five ways you can go about proving that a certain kind of quadrilateral is a parallelogram. The opposite sides are equal in length and the opposite angles are also equal. In this tutorial, take a look at parallelograms and learn what kinds of quadrilaterals can also be called parallelograms ! Suppose that the quadrilateral ABCD in Fig.
