| Geometric Problem Set 001, Betz, Webb and Smith |
These review exercises show the Segment Addition Postulate in its most basic practical form. This is a very straightforward idea. |
 |
|
| Geometric Problem Set 002, Betz, Webb and Smith |
Segment addition follows established logic with incorporation of numbers, or constants, as multipliers or divisors. This is especially easy if you understand fractions. |
 |
|
