Question

lines a and b are parallel lines cut by transversal f. if m∠1 = 110°, what is m∠4? 20° 70° 110° 130°

Explanation:

Step1: Identify angle - relationship

$\angle1$ and $\angle4$ are corresponding angles. When two parallel lines are cut by a transversal, corresponding angles are congruent.

Step2: Determine the measure of $\angle4$

Since $\angle1$ and $\angle4$ are congruent and $m\angle1 = 110^{\circ}$, then $m\angle4=110^{\circ}$.

Answer:

$110^{\circ}$
