Question

L4 is a transversal line to parallel lines L2, L3 and L1, determine which angles are congruent to angle 1 . ( Choose 5 angles)

Answer 1

Answer:

  3, 6, 7, 10, 11

Step-by-step explanation:

The angles congruent to angle 1 are the corresponding angles and their vertical angles.

The corresponding angles are the ones on the north-east corner of the intersection: 1, 7, 11

The angles that are vertical angles with those are ...

  3, 6, 10

So, the angles congruent to angle 1 are 3, 6, 7, 10, 11.
