You cannot name an angle just by its vertex if the point is the vertex of more than one angle. In this case, you must use all three points to name the angle, and the middle point is always the vertex. Jun 39:31 AM Use the diagram to find the measure of each angle.

The Numbers
The numbers we write are made up of algorithms, (1, 2, 3, 4,
etc) called arabic algorithms, to distinguish them from the roman
algorithms (I; II; III; IV; etc.).

The arabs popularise these algorithms, but their origin goes
back to the phenecian merchants that used them to count and do
their commercial contability.
