Question

construct circles of the following radius.
a.4.5 Cm
b.3.2 cm​

Answer 1

Step-by-step explanation:

Draw a circle of radius of 4.5 cm.

Take a point P outside of the circle and take two chords QR and ST.

Draw perpendicular bisectors of these chords and let they intersect at point O.

Join PO and bisect it.

Let U is the mid-point of PO.

Given: Radius of the circle=3.2cm.

(i) With O as the centre draw a circle of radius 3.2cm.

(ii) Take a point P on the circle and join OP.

(iii) Draw an arc of a circle with centre at P cutting OP at L.

(iv) Mark M and N on the arc such that.

(v) Draw the bisector PT of the angle ∠MPN.

(vi) Produce TP to T' to get the required tangent T'PT.
