Lets now apply what we learned and do an exercise together in which we identify parallel and perpendicular lines. Use the properties of parallel lines to determine congruent angles. Intersecting, parallel, and perpendicular lines 2 this worksheet is made for high school lead students eslell new canadians and refugees who have significant gaps in their education. Line n is perpendicular to lines and m, and its slope is the opposite reciprocal of the slopes of and m. And if thats 90 degrees, then thats going to be 90 degrees, thats going to be 90 degrees, and thats going to be 90 degrees. Practiceparallel and perpendicular lines 2 write equation of parallel. Intersecting, parallel, and perpendicular lines 1 this worksheet is designed for lead high school students eslell new canadians and refugees who have significant gaps in their schooling. Two distinct lines in the same plane either are parallel, like line. Parallel and perpendicular lines west jefferson local. Thus, two parallel lines are of type 2 if and only any two points on one line are of nonequal distance from the other line. Horizontal, vertical, parallel and perpendicular lines game free download as word doc.
Finding parallel and perpendicular lines math is fun. Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems e. Parallel and perpendicular lines westby high school. Because lines and m are parallel, their slopes are the same. Demonstrate an understanding of the relationship between geometric representation in a coordinate plane and algebraic models of lines. Introduction the two types of parallels in hyperbolic geometry. If two lines are cut by a transversal so that alternate interior angles are congruent, supplementary, complementary, then the lines are parallel. Finally, we show that as you go away from the common perpendicular, the lines get farther apart. Identifying parallel and perpendicular lines geometry. Infinite algebra 1 graphing parallel and perpendicular lines.
Write and graph the equation that goes through given point a that is parallel to the original line. Geometry worksheets parallel and perpendicular lines worksheets. Our mission is to provide a free, worldclass education to anyone, anywhere. So this is 90 degrees, then these are perpendicular lines. Two lines are parallel if and only if they have the exact same slope. Find the slope of a line parallel to each given line. Math basic geometry lines parallel and perpendicular. In the painting, the artist uses lines and transversals to. Exactly one of these lines is parallel to the given line, and exactly one of them is perpendicular to the given line. Practice test parallel and perpendicular lines page 3 of 5 find the slope of the line that passes through 5, 7 and 2, 9. Through a point not on a line, there are infi nitely many lines.
Write parallel, perpendicular or intersecting below each pair of lines. If two lines are cut by a transversal so that sameside interior angles are congruent, supplementary, complementary, then the lines are parallel. Perpendicular lines form right angles 90 when they intersect. These geometry worksheets are perfect for working with parallel, perpendicular, and skew lines in various problems.
