Question

in the figure to the right, s||t. use the figure to answer the following exercise. ∠b is congruent to which two of the following angles? select all that apply.

Explanation:

Step1: Identify vertical - angle relationship

Vertical angles are congruent. $\angle b$ and $\angle f$ are vertical angles, so $\angle b\cong\angle f$.

Step2: Identify corresponding - angle relationship

Since $s\parallel t$, corresponding angles are congruent. $\angle b$ and $\angle c$ are corresponding angles, so $\angle b\cong\angle c$.

Answer:

$\angle c$, $\angle f$
