For example, the lines, y=3x+8 and y= – (1/3)x-3 would be perpendicular because -1/3 is the opposite reciprocal of 3. To be perpendicular, they only need to have opposite reciprocal slope. No, they can have different y-intercepts. So, we can draw perpendicular lines for a given line in two ways.ĭo you have to have y-intercepts to be perpendicular? We will discuss how to draw the perpendicular lines step by step using a compass and a protractor. To draw a perpendicular line, all we need is a scale (ruler), a compass or a protractor. What do you need to draw a perpendicular line? These lines are either not meeting at all, or intersecting at an angle that is not 90 °. Now, look at the examples of lines that are not perpendicular. Here, the two lines intersect at a right angle, and hence, are said to be perpendicular to each other. Some shapes which have perpendicular sides are: Square Right-angled triangle RectangleĪre there any lines that are not perpendicular to each other? Perpendicular shapes, in geometry, refer to shapes that include perpendicular lines. You can spot the perpendicular lines around you. There are some real-life examples of objects which have perpendicular lines in them. Which is an example of a perpendicular shape? 90° is also called a right angle and is marked by a little square between two perpendicular lines as shown in the figure. What does perpendicular look like?Ī perpendicular is a straight line that makes an angle of 90° with another line. An example of a ray is a sun ray in space the sun is the endpoint, and the ray of light continues on indefinitely.Įxamples of a plane would be: a desktop, the chalkboard/whiteboard, a piece of paper, a TV screen, window, wall or a door. ![]() In geometry, a ray is a line with a single endpoint (or point of origin) that extends infinitely in one direction. The slopes of perpendicular lines are opposite reciprocals of each other. To figure out if two equations are perpendicular, take a look at their slopes. Perpendicular lines intersect at right angles to one another. How do you know if lines are perpendicular? In this case, the slope of the line is and the slope of the line is. If the product of the slopes is, then the lines are perpendicular. How do you show something is perpendicular?Įxplanation: If the slopes of two lines can be calculated, an easy way to determine whether they are perpendicular is to multiply their slopes. Thus, the equation of the line is y = ½x + 6. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. If you are in a room, more than likely you are surrounded by four walls that are all perpendicular to each other. They are in buildings, in rooms, television sets, bookshelves and so on. Real life examples of perpendicular lines surround us. What is a real life example of perpendicular lines? For example, a ┴ b (read as a is perpendicular to b). The symbol used for perpendicular lines are ┴. We can draw a perpendicular line with the help of a set of square. ![]() If two lines meet or intersect at a point to form a right angle, they are called perpendicular lines. What geometric figure shows perpendicular lines?
