SUN ROOM


The diagrams show the plans for a sun room. It will be built onto the wall of a house. The four walls of the sunroom are square clear glass panels. The roof is made using


• Four clear glass panels, trapezium in shape, all the same size


• One tinted glass panel, half a regular octagon in shape



(a) Refer to Top View


Find the mid-point of the segment joining the points J (6, 17) and I (9, 16).


(i) (33/2,15/2)


(ii) (3/2,1/2)


(iii)(15/2,33/2)


(iv) (1/2,3/2)


(b) Refer to Top View


The distance of the point P from the y-axis is


(i) 4 (ii) 15 (iii) 19 (iv) 25


(c) Refer to Front View


The distance between the points A and S is


(i) 4 (ii) 8 (iii)16 (iv)20


(d) Refer to Front View


Find the co-ordinates of the point which divides the line segment joining the points A and B in the ratio 1:3 internally.


(i) (8.5,2.0) (ii) (2.0,9.5) (iii) (3.0,7.5) (iv) (2.0,8.5)


(e) Refer to Front View


If a point (x,y) is equidistant from the Q(9,8) and S(17,8),then


(i) x+y=13 (ii) x-13=0 (iii) y-13=0 (iv)x-y=13



(a)-(iii) (15/2,33/2)

(b) - (i) 4


(c) - (iii)16


(d) - (iv)(2.0, 8.5)


(e) - (ii) x – 13 = 0
