Are Perpendicular Lines Always at a 90-Degree Angle? - legacy
Perpendicular lines intersect at a 90-degree angle, while parallel lines never intersect. Parallel lines have the same slope and are always equidistant from each other.
- Apply geometric principles to real-world problems
- Enhance their knowledge of mathematics and science
To determine if two lines are perpendicular, you can use the criteria mentioned earlier: check if the product of the slopes is -1 or if the lines intersect at a right angle.
Conclusion
Perpendicular lines are lines that intersect at a 90-degree angle. When two lines are perpendicular, they form a right angle, which is a fundamental concept in geometry. To determine if two lines are perpendicular, we can use the following criteria:
