Minor arc
With a central angle of 180° it is a straight line and so the arc is a semi-circle

Jimmel - A Polygon with four or more sides with one tagged side. The tag is on a line and not on an angle. Within the jimmel there is a line between two verticies and all of the sides are straight lines. Dibble - A polygon made up of straight lines where one side is a mirror image to the other. The two sides are separated by a arc-line-arc. If the polygon has equal sides but is not separated by a arc-line-arc then it is not a dibble. All of the sides in a dibble are straight lines. )---------------( = arc-line-arc I think that it is silly for teachers to encourage children to make up words in fifth grade. Especially when I am encouraging my son to look everything up. How foolish would he have felt if I sent him on a search for this definition? Anyway, on the topic of made up words... Frindle by Andrew Clements is a book that my son enjoyed.
The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.
