10) Alternate Interior Angles are angles that are equal, are on opposite sides of the perpendicular line and are on the inside of the two opposite parallel lines.

Hope this helps :)

I ADDED A PICTURE LABELING WHERE THEY ARE!! NEVER FEAR!

Alt. Exteriors are: <1,<8 &<5,<4. Alt Interiors are: <2,<7 &<3,<6.Vertical angles are: <5,<2 &<1,<6 &<3,<8 &<4,<7.Supplementary angles are: <1,<5 &<2,<6 &<3,<7 &<4,<8.If angle 5=40 degrees, then: <1, <3, <6 & <8=130, <2,<7,<4=40.<5, <7 and <4.<2.If angle 1=90, then: all other angles are 90 degrees.Alternate exterior: see picture.Alternate Interior: see picture.

Hope i helped!!
