Question

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).

In the figure, r s.
∠2 ≅ ∠ because they are corresponding angles of parallel lines cut by a transversal. ∠5 ≅ ∠ by the Vertical Angles Theorem.

Answer 1

∠2≅∠6

∠5≅∠8

Explanation:

Answer 2

• ∠2≅∠6 because they are corresponding angles (both are upper right of where the lines intersect)
• ∠5≅∠8 because they are vertical angles (formed by the same pair of lines with only their vertex in common)

Explanation:

You have to be able to apply the definitions of corresponding angles and vertical angles.
