Parallelogram is a polygon with four vertices (corners) and four edges (sides) that form two parallel pairs. Using these properties, we can write a system of equations. For example, if only the height and side a is known it is possible to calculate the area but nothing else. Hence, it is proved that any two adjacent or consecutive angles of a parallelogram are supplementary. The parallelogram is a special case of the trapezium. A parallelogram is a quadrilateral with opposite sides parallel. First, look at the opposite angles, or the angles that are across from each other. India’s favourite sweet kaju katli is an example of a parallelogram. a.

The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. The main difference between a rectangle and a parallelogram that makes rectangle a special case of the parallelogram is the fact that all the angles of a rectangle are equal to 90 degrees. It is not possible for a triangle to have more than one vertex with internal angle greater than or equal to 90°, or it would no longer be a triangle. The opposite sides of parallelogram are parallel and equal in length.

The opposite angles of parallelogram are equal (a is equal with a and b is equal with b). The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. A parallelogram has four sides where the opposite sides are parallel. Calculate the hugest interior angle. Then, complete the conjecture below. ∴ x + 2x = 180° ⇒ 3x = 180° ⇒ x = 60° Thus , the two adjacent angles are 120° and 60°. The bisector of a parallelogram divides one of the angles for parallel lines and secant (which are involved in the construction of the parallelogram), and since these angles add up to 180 °, then at the intersection with the bisector of the adjacent angle we get a perpendicular (90 °).
