Practical Geometry
10.1 INTRODUCTION
You are familiar with a number of shapes. You learnt how to draw some of them in the earlier classes. For example, you can draw a line segment of given length, a line perpendicular to agiven line segment, an angle, an angle bisector, a circle etc. Now, you will learn how to draw parallel lines and some types of triangles.
10.2 CONSTRUCTION OF A LINE PARALLEL TO A GIVEN LINE,THROUGH A POINT NOT ON THE LINE
Let us begin with an activity (Fig 10.1)
(i) Take a sheet of paper. Make a fold. This fold represents a line l.
(ii) Unfold the paper. Mark a point A on the paper outside l.
(iii) Fold the paper perpendicular to the line such that this perpendicular passes through A. Name the perpendicular AN.
(iv) Make a fold perpendicular to this perpendicular through the point A. Name the new perpendicular line as m. Now, l || m. Do you see ‘why’?Which property or properties of parallel lines can help you here to say that lines l and m are parallel.
You can use any one of the properties regarding the transversal and parallel lines to make this construction using ruler and compasses only.
Step 1 Take a line ‘l ’ and a point ‘A’ outside ‘l ’ [Fig10.2 (i)].
Step 2 Take any point B on l and join B to A [Fig 10.2(ii)].
Step 3 With B as centre and a convenient radius, draw an arc cutting l at C and BA at D [Fig 10.2(iii)].
Step 4 Now with A as centre and the same radius as in Step 3, draw an arc EF cutting AB at G [Fig 10.2 (iv)]
Step 5 Place the pointed tip of the compasses at C and adjust the opening so that the pencil tip is at D [Fig 10.2 (v)].
Step 6 With the same opening as in Step 5 and with G as centre, draw an arc cutting the arc EF at H [Fig 10.2 (vi)].
Step 7 Now, join AH to draw a line ‘m’ [Fig 10.2 (vii)].
Note that ∠ABC and ∠BAH are alternate interior angles. Therefore m|| l
