12)a)57. b)33
14)a)4/3. b)11/18
Answer:
Part - A
1) circumference
2) We know that in a parallelogram, opposite sides are parallel as well as equal and opposite angles are equal. In a square, opposite sides are parallel as well as equal and opposite angles are equal to right angle. So, a square is also a parallelogram.
3) 4 right angle
4) -4
5) -10 -(-13)
= -10 +13
= +3
7
6) 16/9 = 1 –
9
7) 0.29 + 0.39 = 0.68
8) straight angle
9) 6 faces
Part - B
3
11) a) 3/8 + 3 –
4
= 3/8 + 15/4
= 3/8 + 30/8
= 33/8
b) 2/3 + 4/6 + 1/2
= 4/6 + 4/6 + 3/6
= 11/6
12) a) 38 -(-19)
= 38 + 19
= +57
b) (-12) -(-45)
= -12 + 45
= +33
13) a) scalene triangle
b) right - angled triangle
14) a) 8/6 = 4/3
b) 44/72 = 11/18
