Lecture 2 : Euclidean geometry
... about two (finite) segments being equal to mean that their lengths match. However Euclid avoided using the word length. However he did add, subtract and compare the things, for which he used the notion of “equality”. 1.1.10. Neutral Geometry. Suppose we were to develop a geometry assuming only the f ...

12 Solving Percents Using Proportions
... As long as we have numbers in three of the four positions in this proportion, we can solve to find the fourth. Fill in the three parts of the proportion that are given. Write a variable for the “what number” or “what percent” part of the question. Now solve like any other proportion. Multiply the di ...
