In the figure,(p)parallel(q) and (r)pparallel(s). Match each pair of congruent angles with the reason for their congruency.


Answer:
∠1≅∠5 by Corresponding angles for parallel line p and q cut by traversal r
∠5≅∠13 by Corresponding angles for parallel line r and s cut by traversal q
∠10≅∠14 by Corresponding angles for parallel line p and q cut by traversal s
∠13≅∠16 by Vertical angles theorem
The given pairs of congruent angles can be matched with their reasons as follows:
Given:
[tex]r \parallel s\\\\p \parallel q[/tex]
From the image,
1. [tex]\angle 5 $ and \angle 13[/tex] share the same corner along transversal q that cuts across lines r and s. Hence, both angles correspond to each other.
2. [tex]\angle 10 $ and \angle 14[/tex] share the same corner along transversal s that cuts across lines p and q. Hence, both angles correspond to each other.
3. [tex]\angle 13 $ and \angle 16[/tex] share the same vertex angle and are just directly opposite each other. Thus, they are vertically opposite each other and are therefore equal by the vertical angles theorem.
4. [tex]\angle 1 $ and \angle 5[/tex] share the same corner along transversal r that cuts across lines p and q. Hence, both angles correspond to each other.
In summary, the given pairs of congruent angles can be matched with their reasons as follows:
