Which of the following statements are true? Select all that apply. Line p and q are parallel lines. Line r and s are also parallel line crosses the line p and q in shape of X. When line q and line r crossed the left side angle 1 is same as the left side angle 8 between crossed line p and line s. Also these angles are same as the corresponding angle 7 formed when line q and line s are crossed. The right side angle 2 formed between crossed lines q and r is same as the right side angle 4 between crossed lines q and s and right side angle 3 between crossed lines p and r. The angle 5 formed below when line p and line r crossed is same as angle 6 formed above when line p and line s are crossed.
A. p || q if ∠2 ≅ ∠3.
B. p || q if ∠5 ≅ ∠7.
C. r || s if ∠2 ≅ ∠4.
D. r || s if ∠5 ≅ ∠6.
