# When two straight lines intersect, four corners are formed, one of them is 130 degrees

When two straight lines intersect, four corners are formed, one of them is 130 degrees, find the values of the remaining other angles.

We know that when two straight lines intersect, one of the angles is formed equal to 130 °. In order to find the degree measures of the remaining angles, you and I must first of all remember which angles are formed at the intersection of straight lines and what property they have.

So, when two straight lines intersect, we get two pairs of vertical angles that are equal to each other.

That is, we get a pair of 130 ° angles.

Also, when crossing, adjacent angles are formed (their sum is 180 °).

x + 130 = 180;

x = 180 – 130;

x = 50 °.

And a pair of 50 ° vertical angles.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
