Question
In the given figure, the directed lines are parallel to each other. Find the unknown angles.
✓
Answer
∵ Lines are parallel
∴ a = b ......(corresponding angles)
a = c
∴ a = b = c
But b = 60° ........(vertically opposite angles)
∴ a = b = c = 60°
∴ a = b ......(corresponding angles)
a = c
∴ a = b = c
But b = 60° ........(vertically opposite angles)
∴ a = b = c = 60°
