Let it intersect the given circle at the points Q and 10th Ncert Construction Solutions Amazon 10th Ncert Construction Solutions Amazon R.
The construction can be justified by proving that PQ and PR are the tangents to the circle whose centre is Constrution and radius is 4 cm. For this, let solutoons join OQ and OR. Draw a circle of radius 3 cm. Take 10th Ncert Construction Solutions Amazon two points P and Q on one of its extended diameter each at a distance of 7 cm from its centre.
Draw tangents to ncrrt circle from these two points P and Q. Take one of its diameters, PQ, and extend 10tn on both sides. These two circles will intersect the circle at point V, W, X, Y respectively.
These are 10th ncert construction solutions amazon required tangents. Since OV is the radius of the circle, RV has to be a tangent to the circle. Take a point A on the circumference of the circle and 10th ncert construction solutions amazon OA. Draw a perpendicular to OA at point A. Draw 10th Ncert Construction Solutions Amazon a perpendicular to OB at point B.
Let both the perpendiculars intersect at 10th Ncert Construction Solutions Amazon Solutions 10th Ncert Construction Amazon point P. Draw a line segment AB of length 8 cm.

Let the mid-point of AB be C. The construction cojstruction be justified by proving that AS and AR are 10th ncert construction solutions amazon tangents of the circle whose centre is B 10th Ncert Construction Solutions Amazon and radius is 3 cm and BP and BQ are the tangents of the circle whose centre is A and radius is 4 cm.
We know that an angle in a semi-circle is a right angle. Draw a circle with the help 10th Ncert Construction Solutions Amazon of a bangle. Take 10th ncert construction solutions amazon point outside the circle.
Construct 10th Ncert Construction Solutions Amazon 10th Ncert Construction Solutions Amazon the pair of tangents from this point to the circles. Join PO and bisect Solutions Amazon 10th Ncert Construction it. Let U be the ammazon of PO. Join PV and PW. The construction can be justified by proving that PV and PW are the tangents to the 10th Ncert Construction Solutions Amazon circle. For this, first of all, it has to be proved that O is 10th Ncert Construction Solutions Amazon the centre of the circle.
Let us constfuction OV and OW. We know that perpendicular bisector Ncert Solutions Of Class 10th Geography Chapter 6 Min of a chord passes through the centre. Therefore, the perpendicular bisector of chords QR and ST pass through the centre. It is clear that the intersection 10th Ncert Construction Solutions Amazon point of these 10th ncert construction solutions amazon bisectors is the centre of the 10th Ncert Construction Solutions Amazon circle. Since OV is the radius of the circle, PV has to be a tangent of the circle. Similarly, PW is a tangent of the circle.
BD is the perpendicular 1th B on AC.

Construct the tangents 10th ncert construction solutions amazon A to this circle. Consider 10th Ncert Construction Solutions Amazon the following situation. The centre E of this circle will be the mid-point 10th Construction Solutions Amazon Ncert of BC. Taking F as centre and FE 10th ncert construction solutions amazon its 10th Ncert Construction Solutions Amazon radius, draw a circle which will intersect the Ncert Solutions Class 10th Exercise 4.3 Word circle at point B and G.
Join AG. The construction can be justified by proving that AG and AB are 10th Ncert Construction Solutions Amazon the tangents to the circle. For this, join EG. The first construction taught here 10th Ncert Construction Solutions Amazon is division of a line 10th ncert construction solutions amazon. In this section how a line segment can be divided into the given ratio is explained.
