If two lines intersect at a point, what is the sum of the angles formed at that

If two lines intersect at a point, what is the sum of the angles formed at that point?

If two lines intersect at a point, what is the sum of the angles formed at that point?

Step 1: Understand that when two lines cross each other, they create angles at the point where they meet.
Step 2: Identify that these angles can be grouped into pairs called vertically opposite angles.
Step 3: Recognize that each pair of vertically opposite angles is equal in measure.
Step 4: Note that there are two pairs of vertically opposite angles formed by the intersecting lines.
Step 5: Realize that the total angles around a point is 360 degrees.
Step 6: However, the angles formed by the two intersecting lines can be grouped into two pairs that each sum to 180 degrees.
Step 7: Conclude that the sum of the angles formed by the intersecting lines at that point is 180 degrees.
