breadth___when something includes many different items, features, subjects or qualities
extend___to (cause something to) reach, stretch or continue; to add to something in order to make it bigger or longer
denoted___to represent something
line segment___A closed interval corresponding to a finite portion of an infinite line. Line segments are generally labeled with two letters corresponding to their endpoints, say and , and then written AB. The length of the line segment is indicated with an overbar, so the length of the line segment AB would be written AB.
planes___A plane is a two-dimensional doubly ruled surface spanned by two linearly independent vectors. The generalization of the plane to higher dimensions is called a hyperplane. The angle between two intersecting planes is known as the dihedral angle.
solids___completely hard or firm all through an object, or without any spaces or holes:
angle___Given two intersecting lines or line segments, the amount of rotation about the point of intersection (the vertex) required to bring one into correspondence with the other is called the angle between them. Angles are usually measured in degrees (denoted ), radians (denoted rad, or without a unit), or sometimes gradians (denoted grad).
situations___ the set of things that are happening and the conditions that exist at a particular time and place
rays___There are several definitions of a ray. When viewed as a vector, a ray is a vector AB from a point A to a point B . In geometry, a ray is usually taken as a half-infinite line (also known as a half-line) with one of the two points A and B taken to be at infinity.
rotation___The turning of an object or coordinate system by an angle about a fixed point. A rotation is an orientation-preserving orthogonal transformation. Euler's rotation theorem states that an arbitrary rotation can be parameterized using three parameters. These parameters are commonly taken as the Euler angles. Rotations can be implemented using rotation matrices.
vertex___The vertex figure at a vertex V of a polygon is the line segment joining the midpoints of the two adjacent sides meeting at V . For a regular n-gon with side length a, the length v of the vertex figure is
degree___The most common meaning is the unit of angle measure defined such that an entire rotation is 360. This unit harks back to the Babylonians, who used a base 60 number system360. likely arises from the Babylonian year, which was composed of 360 days (12 months of 30 days each). The degree is subdivided into 60 minutes per degree, and 60 seconds per minute. In Mathematica, the symbol giving the number of radians in one degree is Degree.
minute___any of the 60 parts which an hour is divided into, consisting of 60 seconds
second___a short unit of time which is equal to a sixtieth of a minute
acute___describes an angle that is less than 90 degrees
right angle___A right angle is an angle equal to half the angle from one end of a line segment to the other. A right angle is n/2 radians or 90 dgree . A triangle containing a right angle is called a right triangle. However, a triangle cannot contain more than one right angle, since the sum of the two right angles plus the third angle would exceed the 180 dgree total possessed by a triangle.
obtuse angle___(of an angle) more than 90° and less than 180°
straight angle___Two right angles make a straight angle, and two straight angles make a full angle.
reflex angle___A reflex angle is an angle of more than 180 dgrees .A full angle is therefore a reflex angle, while acute, obtuse, right, and straight angles are not.
daily___happening on or relating to every day
