- 12. Therefore, lines are parallel if they are on the same plane, and do not intersect with each other. So parallel lines should be
- 13. Two lines parallel if and only are coplana they PARALLEL LINES
- 14. line that sects two or ore lines TRANSVERSAL
- 16. 1 2 3 4 6 7 8 5 l i k Interior Angles - are angles in the inner part of the parallel lines cut by a transversal.
- 17. Exterior Angles 1 2 3 4 6 7 8 5 - are angles in the outer part of the parallel lines cut by a transversal i k l
- 18. Pair of Angles: • corresponding angles • alternate interior angles • alternate exterior angles • same side interior angles • same side exterior angles.
- 19. 1 2 3 4 6 7 8 5 l i k Correspondi ng Angles - are two angles in the same relative position on two parallel lines when those lines are cut by a transversal. - Congruent angles
- 20. 1 2 3 4 6 7 8 5 i k Alternate Interior Angles - are two non- adjacent interior angles in the opposite sides of the transversal. - Congruent angles
- 21. Alternate Exterior Angles 1 2 3 4 6 7 8 5 - are two non- adjacent exterior angles in the opposite sides of the transversal. - Congruent angles
- 22. Same Side Interior Angles 1 2 3 4 6 7 8 5 - are angles that are formed in the inner part of the same side of the transversal. - Supplementary angles
- 23. Same Side Exterior Angles - are angles that are formed in the outer part of the same side of the transversal. 1 2 3 4 6 7 8 5 - Supplementary angles
- 25. Game Time!
- 27. Direction: • Class will be divided into 2 groups • All members must have a corresponding number • As I call a number,
- 28. Direction: • I’ll show on the screen the angles or pair of angles, then write your answer on the board • 1st member to answer will
- 38. Generalization • When can we say that two lines are parallel to each other? • What do you call a line that intersects two or more lines? • How about the angles in the inner part of the parallel lines cut by a transversal? • How about the Outer part of it?
