Copy of Naming Angle Positions
Definition: A transversal is a line that intersects 2 other lines at 2 distinct points.
In the applet, the dashed line below is a transversal. (Actually, each of the three lines displayed below is a transversal.)
When a transversal intersects 2 other lines, special names are given to certain pairs of angles.
These angle pairs are called corresponding angles, alternate interior angles, alternate exterior angles, same-side interior angles, and same-side exterior angles.
Explore these angle pairs within the applet below. Then, answer the questions that follow.
Questions:
1) What does the term "same-side" mean in the phrases "same-side interior angles" and "same-side exterior angles"?- there sums of there angles equal 180
2) What does the term "alternate" mean in the phrases "alternate interior angles" and "alternate exterior angles"? - the angles are on the opposite side of the transversal side
3) Which of the four displayed angles would be considered "interior" angles? Why is this?- angles 3 4 5 6 because the are the angles facing inwords of the whole shap
4) Which of the four displayed angles would be considered "exterior" angles? Why is this?-1 2 7 8 because they are facing outwords.
5) How would you describe, in your own words, what it means for a pair of angles to be described as "corresponding angles"?- they share the same transversal
