Construction - 6 - To bisect a given line segment AB is a line segment. The bisector of AB. (i) With A as centre and a suitable radius greater than AB of length, draw arcs on either side of AB. (ii) With the same radius and B as centre, cut the previous pair of arcs at points P ..

Drawing the perpendicular bisector of line segment A..

To construct a triangle when the sum of two sides, the remaining side and the angle between them are given (We assume that the given angle can be constructed with ruler and compass alone) In BC = 3.8 cm, and AB + AC = 6.5 cm (1) Draw BC = 3.8 cm and at B make (2) With ..

To construct an angle equal to a given angle and a point Q on a line PQ. An angle equal to at Q. (i) With B as centre and any suitable radius draw an arc to cut AB at D and BC at E. (ii) With Q as centre and the same radius, draw an arc to cut PQ at ..

Constructions are to be drawn by using ruler and compass only. It must be stressed that not all constructions are possible using a compass and straight edge alon..

'S' is a large spherical conducting shell of radius few meters. C 1 and C 2 are the two supporting pillars. An insulating material like silk acts like a conveyor belt wound over two pulleys P 1 and P 2 . The pulleys move with the help of a motor. B 1 and B 2 are two spray combs. D i..

Solar Furnace This type can be used for cooking. But the time of cooking depends on the intensity of the sunlight and hence the time taken is shorter in the summer and longer in the winter. Rice, pulses and vegetables can be boiled by keeping them inside the box. Baking and frying can be done in re..

Through A, B and C draw lines parallel to BC, AB and AC respectively. Let these lines meet at P, Q and R forming D PQ..

Join AB. Locate O the mid point of AB. Join PA and PB. Join P and ..
