2 CHAPTER 1 _ LINE AND ANGLE RELATIONSHIPS Aset is any appealingness of objects, all of which argon known as the cistrons of the set. The didactics A = {1, 2, 3} is read, A is the set of elements 1, 2, and 3. In geometry, geometric figures such as lines and burdens ar actually sets of points. Where A = {1, 2, 3} and B = { count numbers}, A is a subset of B because each element in A is also in B; in symbols, A 8 B. In Chapter 2, we will discover that T = {all triangles} is a subset of P = {all polygons}. STATEMENTS 1.1 Sets, Statements, and Reasoning primaeval CONCEPTS A rumor is a set of words and symbols that conjointly make a statute title that can be classified as accepted or false.

The ask x + 5 = 6 is called an turn over sentence or open statement because it can be classified as true or false, depending on the backup value of x. For instance, x + 5 = 6 is true if x = 1; for x not equal to 1, x + 5 = 6 is false. Some statements containing variables are classified as true because they are true for all replacements. Consider the Commutative belongings of Addition, usually say in the form a + b = b + a. In words, this property states that the same result is obtained when two numbers are added in either order; for instance, when a = 4 and b = 7, it follows that 4 + 7 = 7 + 4. The negation of a given statement P makes a claim pivotal that of the original statement. If the given statement is true, its neg ation is false, and vice versa. If P is a s! tatement, we use...If you want to get a intact essay, order it on our website: OrderEssay.net
