Answer 1

Answer:

radius & Diameter?

Radius & diameter from circumference (video) | Khan Academy The diameter is a straight line that passes through the center of the circle. The radius is half of the diameter. It starts from a point on the circle, and ends at the center of the circle.

Parallelogram (Definition, Formulas, Properties and Examples) A parallelogram is a two-dimensional geometrical shape, whose sides are parallel to each other. It is a type of polygon having four sides (also called quadrilateral), where the pair of parallel sides are equal in length. Also, the interior opposite angles of a parallelogram are equal in measure.

Number of sides = 4

Number of vertices = 4

Mutually Parallel sides = 2 (in pair)

Area = Base x Height

Perimeter = 2 (Sum of adjacent sides length)

Type of polygon = Quadrilateral
