Intersecting lines are formed when two or more lines share one or more points of intersection. For the lines to intersect, they must have different slopes and be non-parallel. When two lines intersect, two pairs of opposite vertical angles are formed. Here, we will...

Parallel lines are lines that never intersect. These lines are characterized by being equidistant at each corresponding point. We can determine whether two or more lines are parallel by ensuring that their slopes are the same. Here, we will learn more details about...

Perpendicular lines are two lines that intersect each other at an angle of 90°. We can also say that, if two lines are perpendicular, their intersection forms a right angle. Here, we will learn more details of the perpendicular lines. We will learn about its...

The distance between two points can be calculated using the distance formula. In turn, the distance formula is derived using the Pythagorean theorem in the Cartesian plane, where the distance represents the hypotenuse of a right triangle and the distances...

We can calculate the slope of a line using two points that are part of the line. Therefore, we form a fraction, where the numerator corresponds to the change in the y-coordinates of the points and the denominator corresponds to the change in the x-coordinates. Here,...

The midpoint of a line segment is a point that has coordinates that are located exactly in the middle of the two endpoints of the line segment. These coordinates can be found by adding the x-coordinates of the two points and dividing by 2. Similarly, we add the...
