In mathematics, the term "center of dilation" refers to a constant point on a surface from which all other points are either enlarged or compressed. The center of dilation and the scale factor comprise the two properties of a dilation.
A dilation is a type of transformation of a two-dimensional geometric figure that yields an image, which is similar in form to the initial object but varies in size. The scale factor determines the degree or amount to which the object is increased or decreased. The origin of a coordinate plane with the points x = 0 and y = 0 is the most common center of dilation in geometry.Learn More
The term "Equiradical" means "equally radical" and is used in mathematics to describe roots of the same nth. For instance, the square root of 7 and the square root of 2 are equiradical surds because they are both square roots.Full Answer >
The length of an arc of a circle is obtained by using the formula L=?r?/180, where L is the length of the minor arc of the circle, r is the radius of the circle and ? is the angle made by the arc at the center of the circle.Full Answer >
The center of a circle can be determined by finding the point of intersection of the perpendicular bisectors of two of its chords. This is accomplished using a compass and a ruler.Full Answer >
The center of a circle is simply referred to as the center. However, it is often given the distinction of "0" in drawings and formulas of circles. The center of a circle is defined as the point from which all points of the circumference are equidistant.Full Answer >
