# In Exercises 1 to 6, l and m are cut by transversal v . On the basis of the information given, determine whether l must be parallel to m . m ∠ 2 = 65 °     and m ∠ 7 = 65 ° To determine

To verify:

Whether 𝓁 must be parallel to m.

Explanation

Given:

𝓁 and m are cut by transversal v.

m2=65° and m7=65°.

Figure (1)

Approach:

(1) If two lines are cut by a transversal so that two corresponding angles are congruent, these lines are parallel.

(2) The vertically opposite angles are same in measure.

Calculation:

The given statement is, 𝓁 and m are cut by transversal v.

m2=65° and m7=65°

7 and 6 are vertically opposite angles
