3 2 Angles And Parallel Lines Answer Key

Transcript Angles of Parallel Lines Cut by Transversals. And since angles 2 and 4 are vertical, angle 4 must also be 120 degrees. It concludes with using congruent angles pairs to fill in missing measures. Well, THAT was definitely a TURN for the worse! Since angles 1 and 2 are angles on a line, they sum to 180 degrees. The lesson begins with the definition of parallel lines and transversals. It leads to defining and identifying corresponding, alternate interior and alternate exterior angles. They decide to practice going around the sharp corners and tight angles during the day, before they get their loot. Angles 2 and 6 are also corresponding angles. Boost your confidence in class by studying before tests and mock tests with our fun exercises. We can use congruent angle pairs to fill in the measures for THESE angles as well. They can then use their knowledge of corresponding angles, alternate interior angles, and alternate exterior angles to find the measures for ALL the angles along that transversal.

Mathswatch Answers Angles In Parallel Lines

The raccoons crashed HERE at angle 1. Let's take a look at angle 5. Let's show this visually. To put this surefire plan into action they'll have to use their knowledge of parallel lines and transversals. There are a few such angles, and one of them is angle 3.

Parallel Lines And Angles Worksheet Pdf

Learn on the go with worksheets to print out – combined with the accompanying videos, these worksheets create a complete learning unit. 5 A video intended for math students in the 8th grade Recommended for students who are 13-14 years old. The raccoons are trying to corner the market on food scraps, angling for a night-time feast! They DON'T intersect. When parallel lines are cut by a transversal, congruent angle pairs are created. 1 and 7 are a pair of alternate exterior angles and so are 2 and 8. Can you see another pair of alternate interior angles? So are angles 3 and 7 and angles 4 and 8. Do we have enough information to determine the measure of angle 2? Alternate EXTERIOR angles are on alternate sides of the transversal and EXTERIOR to the parallel lines and there are also two such pairs.

Parallel Lines And Angles Pdf

It's time to go back to the drawing stump. Corresponding angles are pairs of angles that are in the SAME location around their respective vertices. That's because angle 1 and angle 3 are vertical angles, and vertical angles are always equal in measure. Look at what happens when this same transversal intersects additional parallel lines. After watching this video, you will be prepared to find missing angles in scenarios where parallel lines are cut by a transversal. That means angle 5 is also 60 degrees. Based on the name, which angle pairs do you think would be called alternate exterior angles? We are going to use angle 2 to help us compare the two angles. Since angle 6 and angle 4 are both equal to the same angle, they also must be equal to each other! On their nightly food run, the three raccoons crashed their shopping cart... AGAIN. For each transversal, the raccoons only have to measure ONE angle.

Angles In Parallel Lines Question And Answers

The measure of angle 1 is 60 degrees. All the HORIZONTAL roads are parallel lines. In fact, when parallel lines are cut by a transversal, there are a lot of congruent angles. After this lesson you will understand that pairs of congruent angles are formed when parallel lines are cut by a transversal. That means the measure of angle 2 equals the measure of angle 6, the measure of angle 3 equals the measure of angle 7, and the measure of angle 4 equals the measure of angle 8. We already know that angles 4 and 6 are both 120 degrees, but is it ALWAYS the case that such angles are congruent?

Angles In Parallel Lines Worksheet Answers

If two parallel lines are cut by a transversal, alternate exterior angles are always congruent. 3 and 5 are ALSO alternate interior. Now we know all of the angles around this intersection, but what about the angles at the other intersection? Before watching this video, you should already be familiar with parallel lines, complementary, supplementary, vertical, and adjacent angles. Learn about parallel lines, transversals and their angles by helping the raccoons practice their sharp nighttime maneuvers! Now, let's use our knowledge of vertical and corresponding angles to prove it.

The raccoons only need to practice driving their shopping cart around ONE corner to be ready for ALL the intersections along this transversal. Can you see other pairs of corresponding angles here? But there are several roads which CROSS the parallel ones.
