2a : a geometric form (such as a line, triangle, or sphere) especially when considered as a set of geometric elements (such as points) in space of a given number of dimensions a square is a plane figure.

Line. A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is sometimes called a straight line or, more archaically, a right line (Casey 1893), to emphasize that it has no "wiggles" anywhere along its length.

The surface area is the area that describes the material that will be used to cover a geometric solid. When we determine the surface areas of a geometric solid we take the sum of the area for each geometric form within the solid. The volume is a measure of how much a figure can hold and is measured in cubic units.

A space figure or three-dimensional figure is a figure that has depth in addition to width and height. Everyday objects such as a tennis ball, a box, a bicycle, and a redwood tree are all examples of space figures. Some common simple space figures include cubes, spheres, cylinders, prisms, cones, and pyramids.

Answer: A plane figure is two-dimensional, and a solid figure is three-dimensional. The difference between plane and solid figures is in their dimensions. ... The same shape takes on extra dimension by adding additional points and lines to give the shape height, width and depth.

Solid. A closed three-dimensional figure (which may, according to some terminology conventions, be self-intersecting). Kern and Bland (1948, p. 18) define a solid as any limited portion of space bounded by surfaces. Among the simplest solids are the sphere, cube, cone, cylinder, and more generally, the polyhedra.

Surface area is the sum of the areas of all the faces of the solid figure. Finding surface area of solid figure is like finding how much wrapping paper that is required to cover the solid; it is the area of the outside faces of a box. ... Volume is the amount of space inside of the solid figure.

read between the lines. Fig. to infer something (from something else); to try to understand what is meant by something that is not written explicitly or openly. After listening to what she said, if you read between the lines, you can begin to see what she really means. Don't believe every thing you read literally.

Mathematics is the science that deals with the logic of shape, quantity and arrangement. Math is all around us, in everything we do. ... The needs of math arose based on the wants of society. The more complex a society, the more complex the mathematical needs.

Volume is measured in "cubic" units. The volume of a figure is the number of cubes required to fill it completely, like blocks in a box. Volume of a cube = side times side times side.

phrase. If the different parts of a map, drawing, or model are to scale, they are the right size in relation to each other.

When two-dimensional figures are shown on the coordinate plane, a mix of counting and the Pythagorean Theorem can be used to determine the lengths of each side. Then add up the lengths to determine the perimeter or use the basic area formulas for triangles and rectangles to determine the area of the figure.

A vertex (plural: vertices) is the corner that is formed where the ends of the line segments of two or more faces meet. A sphere is a solid figure that has no faces, edges, or vertices. This is because it is completely round; it has no flat sides or corners. A cone has one face, but no edges or vertices.

Algebra is an area in mathematics that uses variables, in the forms of letters and symbols, to act as numbers or quantities in equations and formulas. Geometry is an area in mathematics that studies points, lines, varied-dimensional objects and shapes, surfaces, and solids.

A good definition for shape, according to gemoetry is: a shape has two or more point, a line being the simplest. In light of these points, a line is the most basic shape, but shapes can be extremely complex. Several lines can create shapes, such as a square or a triangle.

'calculate' came from Latin calculus, meaning (not the contents of MTH 141, but) "pebble"(!), since counting was done with pebbles originally! The verb 'to figure' means "to use figures to reckon", where the noun 'figure' seems originally to have meant "numerical symbol".

Line is the most basic visual element. Lines can be used to define shapes and figures, but also to indicate motion, emotion, and other elements.
