This is the first in a series of geometry courses in mathematics for general studies. It explains more about geometric concepts Euclidean geometry and congruent triangles. The material begins by introducing you to symbolic logic. Logical statements can be analyzed using symbols. When we try to draw conclusions from statements we find that their meanings and relationships to other statements are not always clear. By representing these statements using symbolic logic we can more easily come to valid conclusions. Conditional statements make appearances everywhere. In our everyday lives events can easily be represented by the expression ‘If P then Q’. Conditional statements are indeed important and you will learn about the differences between them and biconditional statements. A truth table has columns that are statements and rows that are possible scenarios. It contains every possible scenario and the truth values that would occur. This course outlines the importance of truth tables tautologies and equivalence relations. Formal proofs consist of a sequence of statements that are used to demonstrate the logical necessity of a given conclusion. You will learn how to prove the validity of an argument.You are then introduced to the study of critical thinking which allows us to prove statements are true. Instead of making a truth table for every argument we may be able to recognize certain common forms of arguments that are valid or invalid. If we can determine that an argument fits one of the common forms we can immediately state whether it is valid or invalid. These laws of inference allow us to prove mathematical statements are true. In propositional logic and Boolean algebra De Morgan's laws are a pair of transformation rules that are both valid rules of inference. The rules allow the expression of conjunctions and disjunctions purely in terms of each other via negation. You will learn about the application of this law and the different ways in which it is defined. Quantifier expressions are marks of generality. They come in a variety of categories in English but determiners - like all each some many most and few - provide some of the most common examples of quantification.Next this course introduces you to Euclidean geometry a mathematical system attributed to Greek mathematician Euclid. You will learn about the relationships between figures in both 2-dimensional planes and 3-dimensional spaces. Although there are many types of geometries that are based on different surfaces the planar surface best approximates the small surfaces we deal with on a daily basis. To create a geometric system a postulate system needs to be established. Euclid created a set of assumptions or postulates from which he drew conclusions - these are the rules we will use in studying Euclidean geometry. Next you study congruent triangles. In geometry two figures or objects are congruent if they have the same shape and size or if one has the same shape and size as the mirror image of the other. You will learn about the methods for proving triangles congruent and the inequalities of a triangle.
