What are the properties that the angles must have if the lines are parallel? Proving Lines Parallel Flashcards. Because it couldn't find a date. Share this document. Proving Lines Parallel Section 3-5. To prove any pair of lines is parallel, all you need is to satisfy one of the above.
What have we learned? All we need here is also just one pair of alternate interior angles to show that our lines are parallel. Terms in this set (11). Resources created by teachers for teachers. 'Interior' means that both angles are between the two lines that are parallel.
So we look at both intersections and we look for matching angles at each corner. So if you're still picturing the tracks on a roller coaster ride, now add in a straight line that cuts across the tracks. Scavenger Hunt Recording Sheet. Jezreel Jezz David Baculna. That is all we need. Report this Document. It's like a teacher waved a magic wand and did the work for me. 3-5 practice proving lines parallel answers. Other Calculator Keystrokes.

Joke Time How do you know when it's raining cats and dogs? Problem of the Week Cards. Document Information. 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. These must add up to 180 degrees. This is your transversal. Practice 3 1 properties of parallel lines. Yes, here too we only need to find one pair of angles that is congruent. Did you find this document useful? I would definitely recommend to my colleagues.
So, a corresponding pair of angles will both be at the same corner at their respective intersections. So, for example, if we found that the angle located at the bottom-left corner at the top intersection is equal to the angle at the top-right corner at the bottom intersection, then we can prove that the lines are parallel using this statement. We have four original statements we can make. 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. Through a point outside a line, there is exactly one line perpendicular ot the given line. This is what parallel lines are about. Is this content inappropriate? Theorem 2 lines parallel to a 3 rd line are parallel to each other. Will the football pass over the goal post that is 10 feet above the ground and 45 yards away? 3 5 practice proving lines parallel universe. 12. are not shown in this preview. Parallel Lines Statements. We started with 'If this, then that, ' and we ended up with 'If that, then this. '
Now, with parallel lines, we have our original statements that tell us when lines are parallel. To unlock this lesson you must be a Member. I feel like it's a lifeline. That a pair of alternate exterior angles are congruent.
Last but not least, if the lines are parallel, then the interior angles on the same side of the transversal are supplementary. For parallel lines, these angles must be equal to each other. You will see that the transversal produces two intersections, one for each line. 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, 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. This is similar to the one we just went over except now the angles are outside the pair of parallel lines. When you step in a poodle! 3-5_Proving_Lines_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. In a plane, if 2 lines are perpendicular to the same line, then they are parallel. The path of the kicked football can be modeled by the graph of. If the lines are parallel, then the alternate exterior angles are congruent. A football player is attempting a field goal.
Share with Email, opens mail client. These are the angles that are on the same corner at each intersection. Sets found in the same folder. Original Title: Full description. © © All Rights Reserved. So these angles must likewise be equal to each for parallel lines.
Where x is the horizontal distance (in yards) traveled by the football and y is the corresponding height (in feet) of the football. Save 3-5_Proving_Lines_Parallel For Later. The process of studying this video lesson could allow you to: - Illustrate parallel lines. Here, the angles are the ones between the two lines that are parallel, but both angles are not on the same side of the transversal. The resource you requested requires you to enter a username and password below: Students also viewed. 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. 0% found this document useful (0 votes). When the lines are indeed parallel, the angles have four different properties.
4 If 2 lines are cut by a transversal so that corresponding angles are congruent, then the lines are parallel. You will see that it forms eight different angles. Register to view this lesson. 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. Do you see how they never intersect each other and are always the same distance apart? Share or Embed Document.
