Because Alternate Interior angles are equal.

Step-by-step explanation:

STEP - I:

Reason:

This is the given data.

STEP - II:

It has multiplied and the reason is mentioned as well.

STEP - III:

= 45° + 135° = 180°

Reason:

It has substituted the value of from the previous step. The sum of and is 180°.

STEP - IV:

Reason:

We calculated to be 135°.

Note that and are on the same line. That means their sum should be 180°.

i.e., = 180°.

135° + = 180°.

45°.

One of the ways to prove is to check if alternate interior angles are equal.

Here, and are alternate interior angles and they are equal.
