Answer:
if ∠1 = 70°, then ∠5= 70°
Hence, option (A) is correct.
Step-by-step explanation:
Given
∠1 = 70°
To determine
We need to determine angle ∠5
From the diagram, it is clear that a transversal line crosses the two parallel lines, the angles in the matching corner would be corresponding angles.
- We know that when two lines are parallel, their corresponding angles are equal.
As angle ∠5 is the corresponding angle of angle ∠1 = 70°.
- Also, the corresponding angles are equal here.
Therefore,
if ∠1 = 70°, then ∠5= 70°
Hence, option (A) is correct.
