When two straight lines , AB , AC , meet each other , their inclination or opening is called an angle , which is greater or less as the lines are more or less inclined or opened . The point of intersection A is the vertex of the angle ...

A number placed before a line , or a quantity , serves as a multiplier to that line or quantity ; thus , 3AB signifies that the line AB is taken three times ; A signifies the half of the angle A. The square of the line AB is designated ...
