Write two addition sentences where the sum is zero. describe the numbers.

1) 0+0=0

2) -7+7=0

Step-by-step explanation:

To Find :Write two addition sentences where the sum is zero.

Solution:

1) 0+0 = 0

Since we know that the sum of 0 and 0 is 0

So, the first addition sentence where the sum is zero. is 0+0=0

2)-7+7=0

Sum of numbers with equal values but opposite signs is 0 i.e. sum of of positive and negative integer with same value is 0.

So,  the second addition sentence where the sum is zero is -7+7=0

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.
