Here first we will draw an angle for given question then only we will find the solution

Here \[\left| \!{\underline {\,

{l1} \,}} \right. = {90^ \circ },\left| \!{\underline {\,

{l2} \,}} \right. = {90^ \circ }\]

Therefore here $l\parallel m$

$l1$ and $l2$ are not parallel to each other, here corresponding angles are equal.

Here also$\left| \!{\underline {\,

x \,}} \right. = \left| \!{\underline {\,

y \,}} \right. $

Here $a\parallel b$

$a,b$ are parallel to each other.

When a transversal intersects two parallel lines, the corresponding angles are equal. The vertically opposite angles are equal. The alternate interior angles are equal. A line that has one definite endpoint is called a ray and extends endlessly in one direction. A ray is named after the endpoint and another point on the ray.
