Seema placed a lighedbulb at point O on the ceiling and directly below it placed a table. Now, she put a cardboard of shape ABCD between table and lighted bulb. Then a shadow of ABCD is casted on the table as A'B'C'D' (see figure). Quadrilateral AB'C'D' in an enlargement of ABCD with scale factor 1:2, Also, AB = 1.5 cm, BC = 25 cm, CD = 24 cm and AD = 2.1 cm; ZA = 105?, ZB = 100?, ZC = 70? and ZD = 85. (a) What is the measurment of angle A'? (i) 105? (ii) 100? (b) What is the lenght of A'B' ? (iii) 70? (iv) 80? (i) 1.5 cm (ii) 3 cm (iii) 5 cm (iv) 2.5 cm (c) What is the sum of angles of quadrilateral A'B'C'D'? (i) 180? (ii) 360? (iii) 270? (iv) None of these (d) What is the ratio of sides A'B' and A'D' ? (i) 5:7 (ii) 7:5 (iii) 1:1 (iv) 1:2 (e) What is the sum of angles of C' and D' ? (i) 105? (ii) 100? (iii) 155? (iv) 140?
