And Angles
Description: Transversal Figure
Image copyright: My Own Creation, 2009, created in Paint
1.Transversal-a line that intersects with another line
2.angle-a figure formed with 2 line segments or rays that make a point
3.parallel- 2 lines that don’t meet
4.Perpendicular-2 straight lines that meet at a right angles.
5.adjacent angle-connected; next to each other
6.Alternate exterior angle- parallel lines that are intersected by a transversal exteriorly.
7.alternate interior angle- parallel lines is intersected by a transversal internally
8.vertical angle-a line that goes up and down
9. acute angle-smaller than 90 degrees
10. Obtuse angle-bigger than 90 degrees
11. Right angle-a 90 degree angle
KEY!!!
* Parallel lines-AB and CD
* Transversal line-line segment EF
* Adjacent angle (8)-1&2, 2&3, 3&4, 4&1, 5&6, 6&7, 7&8, 8&5
* Alternate exterior angle (2) - 1&7, 4&6
* Alternate interior angle (2) – 2&8, 3&5
* Vertical angle (4) – 1&3, 2&4, 5&7, 6&8
* Acute angle- 2,4,6,8
* Obtuse angle- 1,3,5,7
* Right angles- none
