When a transversal line cuts through parallel lines equal corresponding and equal alternate angles are formed
A perpendicular bisector intersects a line segment at a right angle, forming two 90-degree angles with the segment. This means that the angle between the bisector and the line segment is always a right angle, indicating that the bisector divides the segment into two equal parts.
180 degrees
180 degrees -- a straight angle
The angle of elevation is looking at an object above your line of sight.
Perpendicular lines.
a line that is 180 degrees. it looks like ______.______ it looks bacialy flat
An angle is the point where two lines meet. A point on a straight line is an "angle" of 180 degrees, so a point at the end of a line might possibly be termed a 0 degree angle, but if it's only 1 line then there isn't really an angle.
Contour line
Two intersecting rays.
A perpendicular line is a type of intersecting line that crosses the other line at a right angle.
A perpendicular bisector line depending on what type of triangle it is.
a 90 digree angle
