1. Two line segments are Congruent if
2. Two angles forming a linear pair are
3. (-5) + (-8) = (-8) +
4. If two angles are complimentary, then the sum of their measures is
5. a+b=b+
10x1
II. Solve the following:
1. Find the product of 3x (-1)
2. (-30) + 10
3. Muliply 7x
4. Which is greater : 2.03 or 2.30
5. Express as rupees 50 paise​

Answer 1

Answer:

1. If two line segments are congruent, that means that they are of equal lengths.

2. Two angles forming a linear pair are 180°.

3.(-5+)+(-8)

(-5+)+(-8)=-5-8

(-5+)+(-8)=-5-8=-13

(-5+)+(-8)=-5-8=-13(-8)+& = -13

(-5+)+(-8)=-5-8=-13(-8)+& = -13=)&=-13+8=-5

4. If two angles are complementary, then the sum of their measures is 90.

5. a+b=b+a is commutative property.

Solve the following:-

1. 3×(-1) = -3

2. (-30)+10 = -20

3. 2.03 is greater because after point there is no value of 0.

4.50 paise = ₹0.50= ₹0.5
