Hi friends, here in this blog we are going to understand an important topic that is Perpendicular Lines. If we have two lines and these lines make the angle of 90 degree with each then the lines are said to be Perpendicular Lines.
Let we have two lines then the slope of one line is negative to the other line. When the slope of one line is ‘s’ then the slope of other line is = -1 / s. let's see how we construct perpendicular lines in geometry.
To plot the perpendicular lines we have to follow some steps, we have to discuss each step one by one.
Step1: To graph perpendicular lines first of all we take a line of any length.
Step2: Then we have to put a point on the line and the point is named as ‘P’.
Step3: For the construction of perpendicular lines we need compass.
Step4: Then using the compass we make an arc on both side of point ‘P’ and both the arc named as ‘U’ and ‘V’.
Step5: Now we have to put the compass on point ‘U’ and measure the length of compass greater than the point ‘P’.
Step6: Then from point ‘U’ make an arc on the upper side of a line.
Step7: Then with the same length we have to make an another arc from point ‘V’ to the upper side of a line. Both arc cross each other.
Step8: Then using pencil we have to draw a line which meets at the cross point.
And we get another line which is perpendicular to the given line and that line makes exactly 90 degree angle to the other line.
We get this figure when we follow all the above steps:
For the pre algebra practice we have to study the different topics in algebra which are number, fractions, factoring, mixed etc. To get good result please focus on sample papers for cbse board and In the next session we will discuss about What are Lines in Geometry.
