Answer 1

Answer:B

Explanation:

Answer 2

B. Transitive property

Explanation:

Transitive property, just like in the case of transitive property of equality, which says that if m = n, and o = m, therefore, o = n.

This property is what is also applied in the given proof above.

Thus:

Since, <1 ≅ <5, and <3 ≅ <5, therefore,

<3 ≅ <5 by transitive property.

The answer is:

✅Transitive property
