               1       To divide a line segment AB in the ratio 5:9, first a ray AX is                 1
                       drawn so that ∠BAX is an acute angle and then at equal
                       distances points are marked on the ray AX such that the
                       minimum number of these points is:
                        (A) 8           (B) 10               (C)14                       D) 1


               2       To divide a line segment AB in the ratio 4:5, a ray AX is drawn                 1
                       first such that ∠BAX is an acute angle and then points A1, A2,
                       A3, ....are located at equal distances on the ray AX and the
                       point B is joined to

                       (A) A12              (B) A11             (C) A10            (D) A9


               3       To construct a triangle similar to a given ΔABC with its sides                  1
                       3/7 of the corresponding sides of ΔABC, first draw a ray BX
                       such that ∠CBX is an acute angle and X lies on the opposite
                       side of A with respect to BC. Then locate points B1, B2, B3, ...
                       on BX at equal distances and next step is to join:
                       (A) B10 to C            (B) B3 to C        (C) B7 to C (D) B4 to C
               4       To draw a pair of tangents to a circle which are inclined to each               1
                       other at an angle of 60°, it is required to draw tangents at end
                       points of those two radii of the circle, the angle between them
                       should be:
                       (A) 135°          (B) 90°             (C) 60°                 (D) 120  0


               5       A pair of tangents can be constructed from a point P to a circle                1
                       of radius 3.5 cm situated at a distance of ___________ from
                       the centre.
                       (A) 5cm            (B) 2cm            (C) 3cm                 (D) 3.5cm

               6       Draw the line segment of length 4.7 cm and a perpendicular bisector of          1
                       it.


               7       Divide a line segment of length 8 cm in the ratio 3 : 4.                        2

               8       Draw a circle of diameter 6.3 cm. Then draw two tangents to the circle          3
                       from a point P at a distance of 7 cm from the centre of the circle.

               9       Construct a triangle similar to a given triangle ABC with its sides equal to    3

                                                            1
