Distance between parallel lines: Draw two lines along the two edges of a scale. You get parallel lines (l and m). Let l || m. ..

The position of the point P in a plane in the rectangular co-ordinate system is determined as follows: Draw PA and PB perpendicular to XX' and YY'. The segment OA = a measures the distance along the x-axis (the x-coordinate and the perpendicular distance AP = OB = b ( parallel to y - a..

Draw a triangle ABC. Draw its angle bisectors. The angle bisectors of a triangle are concurren..

In proving theorems on concurrence, we draw two lines which intersect at a point and draw the third line in such a way that it passes through the point of intersection and then we prove that this straight line obeys the given conditio..

Draw a line through E parallel to p intersecting l in G, n in H respectivel..

Analysis for construction shows Analysis for construction: that you have to draw CF||BD Think how you can complete to meet DE produced at F. a parallelogram with DB and BC as consecutive sides. You will find the need to draw CF||D..

Concurrency of the perpendicular bisectors of the sides of a triangle - Draw a triangle ABC. Draw the perpendicular bisectors of its sides. The perpendicular bisectors of the sides of a triangle are concurrent (pass through the same point). Recall the procedure to draw..

The point of concurrency of the three altitudes of a triangle is called its "Orthocentre". It is generally abbreviated as 'O'. To locate orthocentre it is sufficient to draw altitudes of any two sides of a triangle. The third altitude will then automatically pass through i..

Draw a triangle ABC. Draw its angle bisectors. The angle bisectors of a triangle are concurrent. The point of concurrence is denoted by ..

Draw a triangle ABC. Draw its angle bisectors. The angle bisectors pass through a point. Recall the procedure to draw angle bisectors: With B as centre and with a convenient radius draw an arc of a circle to cut AB and AC at X and Y. With X and Y as c..
