The other side is A) 10 cm  B) 11 cm C) 12 cm  D) 14 cm Correct Answer: C) 12 cm Explanation: By Pythagoras theorem 13² = 5² + x² 169 = 25 + x² x² = 144 x = 12 cm   5. The area of an equilateral triangle is 144√3 cm². Its side is A) 12 cm  B) 18 cm C) 24 cm  D) 36 cm Correct Answer: C) 24 cm Explanation: Area of equilateral triangle =   a2 144 √3=  a2 a² = 576 a = 24 cm   6. Two similar triangles have corresponding sides in the ratio 3 : 5. The ratio of their areas is A) 3 : 5  B) 6 : 10 C) 9 : 25  D) 27 : 125 Correct Answer: C) 9 : 25 Explanation For similar triangles Ratio of areas = Square of the ratio of corresponding sides. A1/A2 = (3/5 )2 = 9/25 A1:A2 = 9 : 25   7. Two similar triangles have areas 64 cm² and 100 cm². The ratio of their corresponding sides is A) 4 : 5  B) 8 : 10 C) 16 : 25  D) 3 : 4 Correct Answer: A) 4 : 5 Explanation:   Ratio of corresponding sides Ratio of corresponding sides = 4 : 5   8. In ΔABC, AB = 7 cm, AC = 9 cm, and BC = 8 cm. The median drawn to side BC divides BC into A) 2 cm and 6 cm       B) 3 cm and 5 cm C) 4 cm and 4 cm      D) 1 cm and 7 cm Correct Answer: C) 4 cm and 4 cm Explanation: A median always divides the opposite side into two equal parts BC = 8 cm Each part = 8/2 = 4 cm   9. The centroid of a triangle divides each median in the ratio A) 1 : 1  B) 1 : 2 C) 2 : 1  D) 3 : 1 Correct Answer: C) 2 : 1 Explanation: The centroid divides every median in the ratio 2 : 1 The longer portion lies between the vertex and centroid Shortcut: Remember Centroid = 2 : 1   10. A right-angled triangle has sides 6 cm, 8 cm and 10 cm. Its inradius is A) 1 cm  B) 2 cm C) 3 cm  D) 4 cm Correct Answer: B) 2 cm Explanation: For a right triangle r= (a + b – c)/2[ r = (6 + 8 –10)/2 = 4/2 =2 ∴ inradius = 2 cm   11. The circumradius of a right-angled triangle whose hypotenuse is 18 cm is A) 6 cm  B) 9 cm C) 12 cm  D) 18 cm Correct Answer: B) 9 cm Explanation: In a right-angled triangle, mid- point of hypotenuse is the Circumcentre Circum Radius = (Length of Hypotenuse)/2 = 18/2 = 9   12. Which of the following can form a triangle? A) 2 cm, 3 cm, 6 cm         B) 4 cm, 5 cm, 10 cm C) 5 cm, 6 cm, 10 cm       D) 1 cm, 2 cm, 4 cm Correct Answer: C) 5 cm, 6 cm, 10 cm Explanation: For a triangle: Sum of any two sides of a tringle is greater than the third side For option C: 5 + 6 > 10; 6 + 10 > 5 ; 5 + 10 > 6 Therefore, it can form a triangle   13.In ΔABC, AD bisects ∠A. If AB = 6 cm, AC = 9 cm and BC = 10 cm, then BD : DC is A) 2 : 3  B) 3 : 2 C) 1 : 2  D) 2 : 1 Correct Answer: A) 2 : 3 Explanation: BD/DC = AB/AC = 6/9 = 2/3 ∴ BD : DC = 2 : 3   14. The base of a triangle is 18 cm and its height is 14 cm. Its area is A) 112 cm²  B) 126 cm² C) 144 cm²  D) 252 cm² Correct Answer: B) 126 cm² Explanation: Area   = 1/2  (base)× (height) = 1/2 (18 ×14) =9×14 =126 cm2   15. The sides of a triangle are 13 cm, 14 cm and 15 cm. Its area is A) 72 cm²  B) 84 cm² C) 96 cm²  D) 105 cm² Correct Answer: B) 84 cm² Explanation: s= (13+14+15)/2=21 ∴ Area of triangle = 84 cm²   16. Two similar triangles have corresponding sides in the ratio 2 : 3. If the perimeter of the smaller triangle is 24 cm, the perimeter of the larger triangle is A) 30 cm  B) 32 cm C) 36 cm  D) 40 cm Correct Answer: C) 36 cm Explanation: Perimeters of similar triangles are in the same ratio as corresponding sides 24/P= 2/3 P=24 × 3/2=36 ∴ 36 cm.    17. A right-angled triangle has hypotenuse 25 cm and one side 7 cm. Its
