The angle is a right angle.
If two lines have angles theta1 and theta2 relative to some third arbitrary line, then the angle between those two lines is theta1 minus theta2. The normal of a line at a point is a line that is 90 degrees from the line going through that point, so the angle between a line and its normal is 90 degrees. As a result, the angle between the two normals of those lines is (theta1 plus 90) minus (theta2 plus 90), which is the same as theta1 minus theta2 because the two plus 90's cancel each other.
Postulates are assumed to be true and we need not prove them. They provide the starting point for the proof of a theorem. A theorem is a proposition that can be deduced from postulates. We make a series of logical arguments using these postulates to prove a theorem. For example, visualize two angles, two parallel lines and a single slanted line through the parallel lines. Angle one, on the top, above the first parallel line is an obtuse angle. Angle two below the second parallel line is acute. These two angles are called Exterior angles. They are proved and is therefore a theorem.

The lines are at the same frequencies
A protractor measures the angle between two lines meeting at a point called a vertex. The angle measurement is in degrees.
If you mean an angle then an angle is formed by two straight lines meeting at a vertex.
An angle
That would be an "angle".
An angle is the measure of rotation required to superimpose one line onto another line. It is typically formed where two lines meet at a point, with the space being the opening or the extent of rotation between these two lines.
The angle is a right angle.
Any shape with two lines meeting at an angle.
a meeting point of two lines that form an angle; a corner.
true or false ? perpendicular lines intersect at an angle of 45
It is not a line. X is two lines meeting in a perpendicular angle(right angle)(90 degrees).
A vertex is a meeting point of two lines forming an angle.
Angle. Also, two lines which intersect at a point can define a plane.
