Question

In the given figure, lines l and m are cut by two transversals n and p. Check whether line l is parallel to line m or not.

Answer 1

Here, $l$ and $m$ are two lines and $p$ is tranversal.

Now, ${38}^o+{42}^o={80}^o$


i.e. the alternate interior angles formed by transversal $p$ with lines $l$ and $m$ are equal.

Hence, $l$ and $m$ are parallel.
