Question

Select the correct pair of angles formed

• A. ∠1 and ∠5 - Corresponding angles
• B. ∠3 and ∠8 - Alternate exterior angles
• C. ∠3 and ∠6 - Co-interior angles
• D. ∠4 and ∠6 - Alternate interior angles

Answer 1

Answer: (A), (C), (D)

∠4 and ∠6 - Alternate interior angles

Corresponding angles are any pair of angles each of which is on the same side of one of two lines cut by a transversal and on the same side of the transversal.

Alternate exterior angles are located outside the two parallel lines on the opposite sides of the transversal.

Co-interior angles lie inside the parallel lines on the same side of the transversal.

Alternate interior angles are the angles which are inside the parallel lines and on alternate sides of the transversal.
In the given figure,
