Line r is parallel to line c. Parallel lines r and c are crossed by lines x and y to form 2 triangles. At parallel line r, the angle formed by x is 5 and the angle formed by y is 4. At parallel line c, the angle formed by x is 3 and the angle formed by y is 2. Angles 1 and 6 are at the intersection of lines x and y. Which angle is congruent to Angle 3? Angle 2 Angle 4 Angle 5 Angle 6
