Solution

The correct option is B
B and C

Locus is the path traced by a moving point, which moves so as to satisfy the certain given condition/conditions.

Here the given circle is of radius 7 cm. The locus of a point which is at a distance of 3 cm from this circle can be:-

A circle of radius = 7 - 3 = 4 cm, which is the circle B in the given figure.

A circle of radius = 7 + 3 = 10 cm, which is the circle C in the given figure.

Q. To construct the tangents from a point to a circle (where O is the centre of the circle and P is the point from which tangents are drawn. Following are the steps of construction in the first list named as “Steps” and the reasons behind those construction in the next list named “Reasons”. Match them accordingly.
STEPS:
i) Join OP.
ii) Bisect the segment OP, at L.
iii) Draw a circle with centre as L and radius LO.
iv) From P, join wherever this circle intersects the original circle.
REASONS:
a) Because angle in a semicircle is

90^{\circ}

and radius is perpendicular to tangent.
b) We get the point(s) of contact, if they exist.
c) To check where the point P lies and hence determining if tangents exist or not.
d) We need to draw a circle with diameter as the distance between the centre of the circle and the point from where tangents should be drawn.

Draw a circle of radius 4 cm and mark two chords AB and AC of the circle of lengths 5 cm and 4 cm respectively, using ruler and compasses only. Then the point of intersection of locus of points, inside the circle, that are equidistant from A and C and the locus of points, inside the circle, that are equidistant from A and B, is the centre of the circle.

Q. Draw a circle of radius 3 cm. Take two points P and Q on one of its extended diameter each at a distance of 7 cm from its centre. Draw tangents to the circle from these two points P and Q.
