Answer 1

Answer:

Step-by-step explanation:

Triangle 1,

Sum of the squares of the shorter lengths = 13² + 17²

                                                                      = 169 + 289

                                                                      = 458

Square of the longest length = 19² = 361

Since, sum of longest side is less than sum of squares of the smaller sides,

13²+ 17² > 19²

Therefore, it's acute triangle.

Triangle 2,

Sum of squares of the shorter lengths = 10² + 24²

                                                                = 576

Square of the largest length = 26² = 576

Since, sum of squares of the shorter lengths = square of the largest length

Therefore, it's a right triangle.
