a straight line from one side of a round object, particularly a circle, passing through the center and joining the other side

the total length of the external boundary of something

(geometry) the length of the external boundary of a curved shape, especially a circle

the measurement of a piece of land or a flat surface

the amount of space that a substance or object takes or the amount of space inside an object

a three-dimensional geometric shape that has a rectangular base and four triangular faces that meet at a single point called the apex

(geometry) a lack of symmetry or equivalence in shape or size between the two sides or parts of something

a point where two or more lines, edges, or rays meet to form an angle, or the point at which the sides of a polygon intersect

a straight line connecting opposite corners of a flat shape at an angle

(in geometry) describing shapes of the same size and form

the side of a geometric shape, usually the one considered as the bottom, from which the height is measured

a pair of geometric figures, such as lines or planes, that do not meet or intersect, no matter how far they are extended

a line that divides a shape into two congruent parts

a series of numbers in which each term after the first is found by multiplying the previous term by a fixed, non-zero number

the total area that the surface of a three-dimensional object occupies

(of a line) intersecting two or more other lines at different points

one-fourth of a circle, formed by two perpendicular radii and the connecting arc

to divide something into two equal parts

a straight line that touches a curve or surface at exactly one point, known as the point of tangency

a straight line segment that connects two points on the edge of a circle

(geometry) to move a shape or figure from one position to another without rotating, resizing, or otherwise altering its shape
