zepdrix (zepdrix):

Mmm I'm not very good at geometry stuff :3 Is it timed? Do you need to answer these quickly?

OpenStudy (anonymous):

Name two pairs of parallel lines in the figure.

OpenStudy (anonymous):

1 hour

zepdrix (zepdrix):

Try to pay attention to the notation used. We use matching symbols to show matching sides/angles/ parallel lines.

OpenStudy (anonymous):

A transversal intersecting two lines creates eight different angles: _____ pairs of corresponding angles, _____ pairs of alternate interior angles,and _____ pairs of alternate exterior angles. A. 2 . . . 2 . . .2 B. 4 . . . 2 . . . 2 C. 2 . . . 2 . . . 4 D. 4 . . . 4 . . . 4

OpenStudy (anonymous):

|dw:1410406227235:dw|Example here. The single slash is to show that the top two sides are equal in length. The double slash is to show that the bottom two sides are equal in length. We do the same with parallel sides, but we use ARROWS instead of slashes. So you tell me, which sides have matching arrows?

OpenStudy (anonymous):

the bottem 2

zepdrix (zepdrix):

No I mean in YOUR picture. :3

OpenStudy (anonymous):

2 lines on the side and the two going up

OpenStudy (anonymous):

zepdrix (zepdrix):

Good yes, k and l have matching arrows, they are parallel to one another. Same with m and n relationship.

OpenStudy (anonymous):

ok
