In the given figures below l is parallel to m. State true or false.

From the given figure:

x + 123 ° = 180 ° ...(Linear Pair) 

$\Rightarrow$ x = 180 ° − 123 ° = 57 °

For the lines 𝑙 and 𝑚 to be parallel to each other, their corresponding angles ∠ABC and ∠BDE should be equal to each other. Here, they are equal.

$\therefore$ l is parallel to m.
