One of the angles obtained by intersecting 2 straight lines = 45 degrees. Find the rest of the angles.

When two straight lines intersect, we get two pairs of vertical angles. And we know that one hundred vertical angles are equal to each other.

We know the degree measure of one of the angles and it is 45 °, then the vertical angle of the mind is also 45 °.

An angle of 45 ° adjacent to the angle formed at the intersection of straight lines.

We know that the sum of adjacent angles is 180 °.

We can find the angle adjacent to 45 ° angles as:

180 ° – 45 ° = 135 °.

This angle also has a vertical to it.

That is, we have two pairs of angles, 45 ° and 135 °.
