To unlock this lesson you must be a Member. 4 If 2 lines are cut by a transversal so that corresponding angles are congruent, then the lines are parallel. 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. Using Converse Statements. Chapter Readiness Quiz. This is similar to the one we just went over except now the angles are outside the pair of parallel lines. Everything you want to read. Document Information. 3 5 practice proving lines parallel lines. So, a corresponding pair of angles will both be at the same corner at their respective intersections.

Ways to Prove 2 Lines Parallel that a pair of corresponding angles are congruent. Now, with parallel lines, we have our original statements that tell us when lines are parallel. 3 5 practice proving lines parallel calculator. See for yourself why 30 million people use. That a pair of alternate exterior angles are congruent. Parallel Lines Statements. What have we learned?

3 5 Practice Proving Lines Parallel Programming

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. You are on page 1. of 13. Remember what converse statements are. Theorem 2 lines parallel to a 3 rd line are parallel to each other. You're Reading a Free Preview. Think of the tracks on a roller coaster ride.

3 5 Practice Proving Lines Parallel Lines

If any of these properties are met, then we can say that the lines are parallel. 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. A football player is attempting a field goal. Resources created by teachers for teachers. 'Interior' means that both angles are between the two lines that are parallel. Is this content inappropriate? Save 3-5_Proving_Lines_Parallel For Later. The path of the kicked football can be modeled by the graph of. Proving lines are parallel pdf. What are the properties that the angles must have if the lines are parallel? Share or Embed Document.

Along with parallel lines, we are also dealing with converse statements. So just think of the converse as flipping the order of the 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. Create your account. Register to view this lesson. Scavenger Hunt Recording Sheet.

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. Through a point outside a line, there is exactly one line perpendicular ot the given 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. 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 transversal creates eight angles that we can compare with each other to prove our lines parallel. 12. are not shown in this preview.

The interior angles on the same side of the transversal are supplementary. Do you see how they never intersect each other and are always the same distance apart? If the alternate exterior angles are congruent, then the lines are parallel.
