Question

Parallel lines r and s are cut by two transversals, parallel lines t and u.

Lines r and s are crossed by lines t and u to form 16 angles. Clockwise from top left, at the intersection of r and t, the angles are 1, 2, 3, 4; at the intersection of s and t, 5, 6, 7, 8; at the intersection of u and s, 9, 10, 11, 12; at the intersection of u and r, 13, 14, 15, 16.

Which angles are corresponding angles with angle 8?
Angle4 and Angle12
Angle2 and Angle10
Angle6 and Angle14
Angle3 and Angle9

Answer 1

Angle 4 and Angle 12.

Angle 8 is the bottom-left angle at the intersection of s and t; corresponding angles are the bottom-left angles at the other intersections (r∩t is angle 4, u∩s is angle 12).
