Answer:

The trick to this problem is that first you have to subtract the digits and then add them. For example:

6 and 4, if we subtract them, we get 2 and if we add them, we get 10, therefore the answer is 210.

9 and 2, if we subtract them, we get 7 and if we add them, we get 11, therefore the answer is 711.

This works for the rest of the numbers as well and we can use it for the unknown problem

8 - 3 = 5

8 + 3 = 11

Therefore, the answer is 511

Answer:

\fbox{511}

<h3>Explanation:</h3>

6+4=(6 - 4)(6 + 4) = 210

9+2=(9  - 2)(9 + 2) = 711

8+5=(8 - 5)(8 + 5) = 313

3+2=(3 - 2)(3 + 2) = 15

following the same pattern,

8+3=(8 - 3)(8 + 3) = 511

A copy of a line segment will have the same measure or length as the segment.

The true statement is (4) They are congruent.

From the question, we understand that a copy of the line segment is created.

This means that the new segment has the exact property as the original line segment.
