concave:curved like a segment of the interior of a circle or hollow sphere
area:any particular extent of space or surface; part
convex:having all interior angles less than or equal to 180°
volume:the amount of space, measured in cubic units, that an object or substance occupies
equiangular:having all the angles equal
equilateral:having all the sides equal: an equilateral triangle
polygon:a figure, especially a closed plane figure, having three or more, usually straight, sides
rhombus:an oblique-angled equilateral parallelogram; any equilateral parallelogram except a square
sphere:a solid geometric figure generated by the revolution of a semicircle about its diameter; a round body whose surface is at all points equidistant from the center
cylinder:a surface or solid bounded by two parallel planes and generated by a straight line moving parallel to the given planes and tracing a curve bounded by the planes and lying in a plane perpendicular or oblique to the given planes
rectangular prism:A solid (3-dimensional) object which has six faces that are rectangles
cube:a solid bounded by six equal squares, the angle between any two adjacent faces being a right angle
segment:a part cut off from a figure, especially a circular or spherical one, by a line or plane, as a part of a circular area contained by an arc and its chord or by two parallel lines or planes
circular:having the form of a circle; round
ratio:the relation between two similar magnitudes with respect to the number of times the first contains the second
proportion:comparative relation between things or magnitudes as to size, quantity, number
angles:the space within two lines or three or more planes diverging from a common point, or within two planes diverging from a common line
postulate:equires no proof, being self-evident, or that is for a specific purpose assumed true, and that is used in the proof of other propositions
triangle:a closed plane figure having three sides and three angles
variable: an equation that may have its value freely chosen without considering values of any other variable
theorems: a theoretical proposition, statement, or formula embodying something to be proved from other propositions or formulas.
