Question

how to make parallel line board​

Answer 1

Answer:

Step 1: Paste the sheet of white paper on the cardboard.

Step 2: Draw a straight line PQ = 10 cm on this paper. At P draw a line MP perpendicular to PQ and at Q draw a line NQ perpendicular to PQ. Graduate the two lines MP and NQ as shown in Figure 6.1.

Step 3: Draw a line XY parallel to PQ by taking points X and Y at an equal distance from P and Q respectively, and then joining them.

Step 4: Cut a triangle ABC from the colored paper and paste it on the white paper so that its side BC coincides with the line XY as shown in Figure 6.1.

Step 5: Draw two straight lines X1Y1 and X2Y2 both parallel to the line PQ (by the procedure discussed in Step 3), such that the line X1Y1 cuts the sides AB and AC at points D1 and E1 respectively, and the line X2Y2 cuts the sides AB and AC at points D2 and E2 respectively.

Step 6: Measure the lengths of the line segments AD1, D1B, AE1, E1C, AD2, D2B, AE2 and E2C, and record them in the observation table.

Answer 2

Steps for parrel line:

Draw a line ( on point P)

Put a point P' outside it (pic attached)

Put a point in da present line

Drag the compass to point P

and draw a curve.

Then,

Put the same compass on P'

and draw a curve

Finally, in line P, put the compass pointer on Q

and draw a curve on Q'

My dear, your work is done.

Give 2 pairs of arrows on the line to indicate it parallel.
