Answer:
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.
