Key Takeaways · Parallel lines have the same slope · Perpendicular lines have slopes that are opposite reciprocals In other words, if m=ab,
Two lines that intersect and form right angles are called perpendicular lines The symbol ⊥ is used to denote perpendicular lines In Figure , line l ⊥ line m The perpendicular lines are two lines that intersect each other and the angle formed between the two lines should be equal to 90 degrees (right
ร้านตามสั่ง 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 A perpendicular is a straight line that makes an angle of 90° with another line 90° is also called a right angle and is marked by a little square between two
