![]() How do You Know if Two Lines Are Perpendicular? Yes, one of the properties of perpendicular lines is that they intersect and touch each other. Parallel lines are those lines that do not intersect anywhere and are always the same distance apart. Perpendicular lines are those lines that intersect each other at right angles (90°). What is the Difference Between Parallel and Perpendicular Lines? It is mathematically expressed as (m1×m2 = -1) or m1 = -1/m2. The perpendicular line formula is defined as the product of two slopes m1 and m2 is -1. To find the slope of two lines we use the perpendicular lines formula. For example, if line CD is perpendicular to line EF, we write it as, CD ⊥ EF. When any two lines are perpendicular, we express them using a perpendicular symbol (⊥). This means when two perpendicular lines intersect each other they form perpendicular angles. ![]() Perpendicular angles can also be referred to as right angles (90°). In other words, when anything is at an angle of 90° to a surface, line, a plane, or ground, it is said to be perpendicular to that surface. Perpendicular means standing at right angles to the plane of the horizon. The symbol used to denote two perpendicular lines: \(\mathbf\).įAQs on Perpendicular Line What is Perpendicular? The symbol used to denote two parallel lines: || Lines that intersect each other forming a right angle are called perpendicular lines.Įxample: the steps of a straight ladder the opposite sides of a rectangle.Įxample: the corner of two walls the letter 'L' ![]() The following table shows the main difference between parallel and perpendicular lines. Difference Between Parallel and Perpendicular Lines For example, zebra crossings on the road or the opposite sides of your ruler, and many others too! The table shown below differentiates between parallel lines and perpendicular lines. You can find parallel lines all around you. The symbol used to show that the lines are parallel is ||, and we express it as: PQ || RS. In the figure, AB is perpendicular to CD and PQ is parallel to RS. Observe the lines shown below to see the difference between perpendicular lines and parallel lines. Two straight lines are said to be parallel if they are equidistant from each other and never meet, no matter how much they may be extended in either directions. Step 5: Join P and Q, which forms a perpendicular on the given line.Step 4: Keeping the same radius, draw two intersecting arcs that intersect at Q by placing the pointer of the compass at C and D.Step 3: Without disturbing the radius of the compass, draw two arcs that cut the semi-circle at C and D by placing the pointer of the compass at A and B respectively.Step 2: Placing the pointer of the compass at P, construct a semi-circle that cuts the line at A and B.Step 1: Adjust the compass to the desired radius.To draw a perpendicular line at a point P on a line, follow the steps given below. We can also draw a perpendicular line using a compass. So, BP is a line that is perpendicular to the given line.ĭrawing a Perpendicular Line Using Compass Step 3: Remove the protractor and join P and B.Step 2: Mark a point B at 90 ° of the protractor.Step 1: Place the baseline of the protractor along the line such that its center is at P.To draw a perpendicular line at point P on the given line, follow the steps given below. ![]() This tool not only helps us measure an angle in degrees, but also helps in drawing perpendicular lines. So, we can draw perpendicular lines for a given line in two ways.ĭrawing a Perpendicular Line Using ProtractorĪ protractor, in math, is considered an important measuring instrument in the geometry box. We will discuss how to draw 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.
