4 SETTING OUT RIGHT ANGLES AND PERPENDICULAR LINES

perpendicular  Two lines, vectors, planes, etc , are said to be perpendicular if they meet at a right angle In R^n, two vectors a and b are perpendicular if their dot Perpendicular lines are two lines that intersect at a right angle You can see them from the corners of tables to sides of buildings Read on to learn more

As shown in Figure 3, if two lines are both perpendicular to a third line , all of the angles formed on the third line are right angles Therefore, Perpendicular lines are represented using the symbol, '⊥' If lines l and m are perpendicular to each other, they intersect each other at

A video explaining how to find and use the equations of perpendicular lines Exam Question The slope of the parallel line is undefined and the slope of the perpendicular line is 0 notebook Example 4: Find the
