Answer:
Lines meeting at right angle.
Step-by-step explanation:
Right angles
- In geometry, the property of being perpendicular is the relationship between two lines which meet at a right angle that is 90 degrees.
- To lines are said to be perpendicular, if they meet at 90 degrees that is the angle between them is 90 degrees.
- A line is said to be perpendicular to another line if the two lines intersect at a right angle.
- If line L is perpendicular to Line M, then it can be written as [tex]L \perp M[/tex]
- If two lines are perpendicular, then the product of slopes of the two lines is equal to -1.
