Don't worry, it's nothing complicated. Proving Lines Parallel Section 3-5. The word 'alternate' means that you will have one angle on one side of the transversal and the other angle on the other side of the transversal. The interior angles on the same side of the transversal are supplementary. Yes, here too we only need to find one pair of angles that is congruent. 3 5 practice proving lines parallel programming. What are the properties that the angles must have if the lines are parallel?
That both lines are parallel to a 3 rd line. These must add up to 180 degrees. © © All Rights Reserved. Buy the Full Version.
Share this document. Lines e and f are parallel because their same side exterior angles are congruent. Create your account. Jezreel Jezz David Baculna.
Problem Solving Handbook. To prove any pair of lines is parallel, all you need is to satisfy one of the above. 'Interior' means that both angles are between the two lines that are parallel. Using Converse Statements to Prove Lines Are Parallel - Video & Lesson Transcript | Study.com. Because it couldn't find a date. I feel like it's a lifeline. Now let's look at how our converse statements will look like and how we can use it with the angles that are formed by our transversal. So, if my angle at the top right corner of the top intersection is equal to the angle at the bottom left corner of the bottom intersection, then by means of this statement I can say that the lines are parallel. So just think of the converse as flipping the order of the statement. We know that in order to prove a pair of parallel lines, lines that never intersect and are always the same distance apart, are indeed parallel, we need a transversal, which is a line that intersects two other lines.
Converse of the Consecutive Interior Angles Theorem If two lines are cut by a transversal such that a pair of consecutive interior angles are supplementary, then the two lines are parallel. Original Title: Full description. For example, if I added the angle at the bottom left of the top intersection to the angle at the top left of the bottom intersection and I got 180 degrees, then I can use this statement to prove my lines are parallel. Proving lines parallel worksheet answers. Scavenger Hunt Recording Sheet. 12. are not shown in this preview.
So, a corresponding pair of angles will both be at the same corner at their respective intersections. The process of studying this video lesson could allow you to: - Illustrate parallel lines. Other Calculator Keystrokes. So if one angle was at the top left corner at one intersection, the corresponding angle at the other intersection will also be at the top left. Proving lines are parallel. Amy has worked with students at all levels from those with special needs to those that are gifted. If any of these properties are met, then we can say that the lines are parallel. What have we learned? All we need here is also just one pair of alternate interior angles to show that our lines are parallel. Chapter Readiness Quiz. Online Student Edition. Resources created by teachers for teachers.
Think of the tracks on a roller coaster ride. Did you find this document useful? 0% found this document not useful, Mark this document as not useful. You will see that it forms eight different angles. Recent flashcard sets. We started with 'If this, then that, ' and we ended up with 'If that, then this. '
0% found this document useful (0 votes). In a plane, if 2 lines are perpendicular to the same line, then they are parallel. For example, if we found that the top-right corner at each intersection is equal, then we can say that the lines are parallel using this statement. So, if the interior angles on either side of the transversal add up to 180 degrees, then I can use this statement to prove the lines are parallel. California Standards Practice (STP). I would definitely recommend to my colleagues. Through a point outside a line, there is exactly one line perpendicular ot the given line. You're Reading a Free Preview.

Will the football pass over the goal post that is 10 feet above the ground and 45 yards away? Click to expand document information.
Amy has a master's degree in secondary education and has been teaching math for over 9 years. These properties are: - The corresponding angles, the angles located the same corner at each intersection, are congruent, - The alternate interior angles, the angles inside the pair of lines but on either side of the transversal, are congruent, - The alternate exterior angles, the angles outside the pair of lines but on either side of the transversal, are congruent, and. This line creates eight different angles that we can compare with each other. You will see that the transversal produces two intersections, one for each line. We have four original statements we can make.
The path of the kicked football can be modeled by the graph of. So if you're still picturing the tracks on a roller coaster ride, now add in a straight line that cuts across the tracks. If 2 lines in a plane are cut by a transversal so that a pair of alternate interior angles is congruent, then the lines are parallel. Now, with parallel lines, we have our original statements that tell us when lines are parallel. See for yourself why 30 million people use. To begin, we know that a pair of parallel lines is a pair that never intersect and are always the same distance apart. Reward Your Curiosity. Other sets by this creator.
That a pair of consecutive interior angles are supplementary. Using Converse Statements. Prove parallel lines using converse statements by creating a transversal line. Cross-Curricular Projects. That a pair of alternate exterior angles are congruent. Parallel Lines Statements. Theorem 2 lines parallel to a 3 rd line are parallel to each other. But in order for the statements to work, for us to be able to prove the lines are parallel, we need a transversal, or a line that cuts across two lines. Save 3-5_Proving_Lines_Parallel For Later.
