What is the angle between lines of force and equipotential lines in an electrical field?
The angle is a right angle.
How it can be proved that angle between two straight lines is equal to the angle between their normals?
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.
What is the difference between a theorem and postulate?
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.

What are the similarities between emission and absorption spectra?
The lines are at the same frequencies
Is an angle the space between two meeting lines?
it is a line segment
What is the unit measured by a protractor?
A protractor measures the angle between two lines meeting at a point called a vertex. The angle measurement is in degrees.
In geometry an angle is formed by what?
If you mean an angle then an angle is formed by two straight lines meeting at a vertex.
What is the v-shaped meeting point of two lines?
An angle
What is the figure formed by two straight lines meeting at a point called?
That would be an "angle".
What is the angle between lines of force and equipotential lines in an electrical field?
The angle is a right angle.
Has at least one corner?
Any shape with two lines meeting at an angle.
What does a vertex form?
a meeting point of two lines that form an angle; a corner.
True or false The slope is equal to the angle of a line?
true or false ? perpendicular lines intersect at an angle of 45
What kind of line is x?
It is not a line. X is two lines meeting in a perpendicular angle(right angle)(90 degrees).
What does a vertex and a line form?
A vertex is a meeting point of two lines forming an angle.
Figure formed by the meeting of two lines in a point?
Angle. Also, two lines which intersect at a point can define a plane.
