are alternate exterior angles, so . is adjacent to , so it must be equal to 180o – 110o = 70o. From here, it’s easy to calculate that f – g = 110o – 70o = 40o. Perpendicular Lines Two lines that intersect to form a right (90o) angle are called perpendicular lines. ...

When two lines intersect to form right (90 degree) angles, we refer to them as perpendicular lines. Perpendicular lines must exist in the same plane. How do you prove that two lines are perpendicular? You can use many mathematical theorems to prove that lines are perpendicular, including the...
Two lines that intersect to form a right (90o) angle are called perpendicular lines. Line segments AB and CD are perpendicular. A line or line segment is called a perpendicular bisector when it intersects a line segment at the midpoint, forming vertical angles of 90o in the process. For ...
The point where lines or line segments intersect is called the point of intersection. When this happens, the lines or line segments are said to be Intersecting Lines. Diagram of intersecting line and line segment Because lines and line segments are straight, linear figures, they cannot intersect...
When two lines intersect, four angles are formed. Among them, two are acute and two are obtuse. Do Parallel Lines Have a Solution? Since parallel lines never cross, there can be no intersection; for a system of equations that graphs as parallel lines, there can be no solution. This is ...
Equations of a Line: Includes various forms such as slope-intercept form (y = mx + c), point-slope form, and general form (Ax + By + C = 0). Parallel Lines: Lines that never intersect and have the same slope. Perpendicular Lines: Lines that intersect at a right angle, with slopes...
Perpendicular means a line at a right angle to another line or plane. What is the opposite of perpendicular lines? What is the symbol for perpendicular lines? What is the equation for a perpendicular line? Take at home math practice to the next level ...
