 Parallel lines have the same slopes and different y-intercepts. They will never cross each other.  Perpendicular lines cross at a right angle and their slopes when multiplied equal -1. Their slopes are opposite reciprocals of each other.  Practice problems Page all

 The total degree of any triangle is always 180º  You need to know how to apply this theorem is given a triangle with an angle(s) missing.  There are 4 different types of triangles based on the type of angles: equiangular, acute, right, and obtuse. There are 3 different types of triangles based on the sides: scalene, isosceles, and equilateral.  You need to know the exterior angle theorem and how to apply it. The exterior angle equals the sum of the two remote interior angles.  Practice problems Page all, 18-20all, all

 You need to know the names of the polygons listed on page 158 in your book. You also need to know the names of a 7, 11, 50 and 100 sided polygon.  Know how to calculate the total sum of angles in a polygon (n – 2)180  For the degrees of AN angle divide it by the number of sides  Remember that ALL polygons have 360°on their exterior angles. If you want to know how many degrees there are at one exterior angle divide it by the number of sides.  Practice problems Page all, 32-36all, 40-43all, 47-49all

 You need to know the slope-intercept form of a line y = mx + b and how to graph using it.  Know how to put an equation into standard form of a line Ax + By = C and graph using it.  Know how to put something into point-slope form of a line (y – y ) = m(x – x )  If given two points you should be able to calculate the slope and put it into point- slope form of a line.  Practice problems Page all, 42-44all

 Parallel lines have the same slope. They will never intersect as long as they have different y-intercepts.  Perpendicular lines have slopes that are the opposite reciprocals of each other. If you multiple the slopes their product will be -1.  You need to be able to write an equation for a perpendicular line if given a line and a point. It needs to be in point-slope form of a line.  Practice problems Page all, 20-22all, 25-28all
