the first and the last line segments form a right angle triangle.

Step-by-step explanation:

For the line segments to form a right angle triangle, then they must form a Pythagoras triple. This means that if we apply Pythagoras theorem, the results would be whole numbers. Pythagoras theorem is expressed as

Hypotenuse² = opposite side² + adjacent side²

1) Considering the first line segment,

53² = 28² + 45²

2809 = 784 + 2025

2809 = 2809

Therefore, the line segment would form a right angle triangle.

2) Considering the second line segment,

64² = 33² + 56²

4096 = 1089 + 3136

4096 is not equal to 4225

Therefore, the line segment would not form a right angle triangle.

3) Considering the second line segment,

85² = 77² + 36²

7225 = 5929 + 1296

7225 = 7225

Therefore, the line segment would not form a right angle triangle.
