The angle is the name of the difference in direction between 1 line & another radiating from the same point. The measurement is in degrees. ( 360 degrees in a circle) Or the measurement may be meaured in Mils (6400 mils = a circle) 1 mil is the difference in distance (1 metre) in the circumferance of a circle 1 Km from the centre. The Royal Navy at one time used, I think, 32 points of the compass, NNW, ESE, 10 points to Starboard, Mr Christian ! etc. The angle, therefore, is the measurement of this difference in direction.
Each other of the alternate angles will measure 75 degrees because there are 180 degrees on a straight line.
If two lines intersect each other at right angles, that means that the measure of each angle between the two lines is 90o. Another way of stating this is to say that two lines are perpendicular.

Vertical angles have the same angle measure. Vertical angles are formed by two intersecting lines that look like an "x". Angles that are across from each other on this "x" are called vertical angles.
That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
Longitude lines.
Lines of latitude are imaginary lines used to measure distances north and south of the Equator or 0 degrees.
The lines don't measure anything, any more than the marks on a ruler do. Latitude and longitude are angles on the Earth's surface, measured between zero- references and the location you're trying to find or describe. Some maps and globes have some latitudes and longitudes marked on them, to help you estimate the angles. Just like the marks on a ruler.

The method used to measure lines of longitude and latitude to determine exact location is called geodetic surveying. It involves the use of specialized instruments such as theodolites and GPS receivers to accurately measure angles and distances on the Earth's surface. These measurements are then used to calculate the precise coordinates of a particular location.
