Question

lines a and b are parallel lines cut by transversal t. if m∠1 = 110°, what is m∠4? 20° 70° 110° 120°

Explanation:

Step1: Identify angle - pair relationship

$\angle1$ and $\angle4$ are corresponding angles.

Step2: Apply parallel - lines property

For parallel lines cut by a transversal, corresponding angles are congruent. So $m\angle4 = m\angle1$.

Answer:

C. $110^{\circ}$
