Answer:
False
Explanation:
Since we want to test if it is a right triangle, we can use Pythagorean Theorem
a^2+b^2=c^2
where a and b are the legs, and c is the hypotenuse.
In the given triangle, 23 and 26 are the legs, since they are shorter sides. 42 is the hypotenuse, since it is the longest side.
Therefore, a is 23, b is 26 and c is 42. Substitute these values into the equation
23^2+26^2=42^2
Evaluate the exponents
529+676=1764
Add 529 and 676
1205=1764
This statement is not true, 1205 is not equal to 1764. Therefore this is not a right triangle.
