Answer:
Horizontal Lines, Vertical Lines, Parallel Lines, Perpendicular Lines
Step-by-step explanation:
1. The horizontal line is then used for analytical or trading purposes. For example, if the price of an asset is moving between support and resistance horizontal lines then the price is considered to be range-bound.
2. Vertical Lines in Photographic Composition can transmit force, momentum, growth. If the vertical lines also are repeated, they give rhythm to the photo and it may increase the dynamism. In a photograph, the vertical lines can be identified as very common elements such as the trees, standing people, buildings or other architectural elements.
3. Parallel lines are lines that never intersect. Because of this, a pair of parallel lines have to have the same slope, but different intercepts (if they had the same intercepts, they would be identical lines). So, to find an equation of a line that is parallel to another, you have to make sure both equations have the same slope.
4. Perpendicular when two lines intersect to form a pair of congruent angles If two lines intersect to form a linear pair of "congruent angles", the lines are therefore perpendicular. Congruent angles are just angles that are equal to each other! Theorem 2: Perpendicular when two lines intersect to form four right angles
