Answer: It’s a scalene triangle.
Step-by-step explanation: The three main types of triangles known are, EQUILATERAL (all three sides and angles are equal), ISOSCELES (only two sides and two corresponding angles are equal) and SCALENE (none of the sides and none of the angles are equal). Also, note that it’s not a right angled triangle. A right angled triangle would have an hypotenuse whose square is equal to the addition of the square of the other two sides. For a triangle with dimensions 8, 10 and 13 to be right angled, it must be solved by the formula;
13^2 = 10^2 + 8^2
169 = 100 + 64
169 ≠ 164.
So it’s definitely not a right angled triangle. The triangle with side lengths 8, 10 and 13 is a scalene triangle.
