a portion of a circumference<\/p>\n<\/dd>\n

Auxiliary Line<\/dfn><\/dt>\n
\n

an extra element line added, different from the standard divisions<\/p>\n<\/dd>\n

Bisect<\/dfn><\/dt>\n
\n

to divide in half<\/p>\n<\/dd>\n

Chord<\/dfn><\/dt>\n
\n

a straight line from 2 points on a circumference<\/p>\n<\/dd>\n

Circumference<\/dfn><\/dt>\n
\n

the distance around a circle, perimeter of a circle<\/p>\n<\/dd>\n

Diameter<\/dfn><\/dt>\n
\n

the distance across a circle at center, twice the radius<\/p>\n<\/dd>\n

Elbow Rule<\/dfn><\/dt>\n
\n

the number of pieces of a round elbow times 2 then minus 2(# of pcs x 2-2) gives us the number of gores in the elbow<\/p>\n<\/dd>\n

Element Line<\/dfn><\/dt>\n
\n

a line representing an edge or bend<\/p>\n<\/dd>\n

Elevation View<\/dfn><\/dt>\n
\n

looking at the front or side of something, to have elevation (height), 2D<\/p>\n<\/dd>\n

Frustum<\/dfn><\/dt>\n
\n

a cone with the top cut parallel to the base<\/p>\n<\/dd>\n

Gore<\/dfn><\/dt>\n
\n

a part of a round elbow which allows us to calculate the miter angle<\/p>\n<\/dd>\n

Horizontal<\/dfn><\/dt>\n
\n

a line\/plane level with the horizon. Flat, level<\/p>\n<\/dd>\n

Miter<\/dfn><\/dt>\n
\n

an intersection of 2 pieces- an irregular cut on the end of something<\/p>\n<\/dd>\n

Obtuse Angle\/Triangle<\/dfn><\/dt>\n
\n

an angle\/triangle with an angle larger than 90\u00b0<\/p>\n<\/dd>\n

Parallel<\/dfn><\/dt>\n

Point of Tangency<\/dfn><\/dt>\n
\n

a straight line that touches the circle at only one point<\/p>\n<\/dd>\n

Profile<\/dfn><\/dt>\n
\n

a half of a plan view, drawn on the outside of an object<\/p>\n<\/dd>\n

Quadrant<\/dfn><\/dt>\n
\n

a sector which equals one quarter of the area of a circle<\/p>\n<\/dd>\n

Radius<\/dfn><\/dt>\n
\n

the distance from center to any point of the circumference, half the diameter<\/p>\n<\/dd>\n

the area of a circle bound by an arc and a chord<\/p>\n<\/dd>\n

Slant Height (small or large)<\/dfn><\/dt>\n

the hypotenuse of a cone, outside edge. The slant height is always a true length in the elevation view<\/p>\n<\/dd>\n

Stretch-out<\/dfn><\/dt>\n
\n

a shape which has been \u201cstretched out\u201d, to take a perimeter and make it straight<\/p>\n<\/dd>\n

Stretch-Out Angle\/Arc<\/dfn><\/dt>\n
\n

the angle or arc which encompasses a radial line pattern<\/p>\n<\/dd>\n

Tangent<\/dfn><\/dt>\n
\n

a line which touches only 1 point of a circumference<\/p>\n<\/dd>\n

Triangulation from Plan View<\/dfn><\/dt>\n
\n

the length of an element line, set 90\u00b0 to the vertical height, gives the true length of that line<\/p>\n<\/dd>\n
