Angle Relationships - California State University, Northridge

Angle Relationships Mr. Barrios 4/21/08 Point A point is a spot on a line that is labeled by a letter.

Example of a point is the top of this Golden Gate Bridge. Line A line is straight and moves in two directions infinitely.

If the Golden Gate Bridge went on forever, it would be a line. Line Segment A portion of a line that has two endpoints

points. A line segment would be a portion of the bridge between two towers. Ray A ray begins at a point and moves in a

straight line forever. Shining a flashlight is like a ray. Intersection When two lines cross one and other, the point that is made is

the intersecting point. Two streets that cross each other make an intersecting point. Transversal A line that cuts through another line,

making four angles in doing so. Vertical Angles Vertical angles are made when two lines intersect each other. Because angles 1 & 3 are vertical (their

noses touch), they are congruent. Corresponding Angles Corresponding angles are also congruent. Always on the same side of the transversal.

Every other angle is a corresponding angle. Alternate Interior Angles Alternate interior angles are also congruent. The angles are always in

between the two parallel lines. They are vertical to one and other. Which are alternate interior angles? Alternate Exterior Angles

Very similar to alternate interior angles, except on the outside of the parallel lines. Congruent angles.
