Oct 10, 2023 · Step 1: To draw perpendicular lines with a protractor, use a ruler to draw a straight horizontal line. Step 2: Then, draw a dot somewhere on the horizontal line. For this example, let’s label the dot P. Step 3: Now, place the baseline of the protractor along the horizontal line with the center at P. Step 4: Mark a point, C, at the 90 mark of ...
For perpendicular lines, the slopes must be opposite reciprocals (different signs and fraction inverted). So -3 and 1/3 or 2/3 and -3/2 are pairs of perpendicular slopes. A perpendicular line has a slope of the negative inverse of the original equations slope. If y=2x+1 is the first equation, it has a slope of 2.

House of lines. This is a two-player game. Pick a room in your house! Player 1 gets a point for every pair of parallel lines they can find in the room. Player 2 gets a point for every pair of ...
Parallel lines are lines that never intersect, and they form the same angle when they cross another line. Perpendicular lines intersect at a 90-degree angle, forming a square corner. We can identify these lines using angles and symbols in diagrams. Created by Sal Khan and Monterey Institute for Technology and Education.
