Answer:
No
Explanation:
Since a right triangle's hypotenuse is the longest side, you can assume that 93mm would be the hypotenuse.
You plug these numbers into the Pythagorean theorem (a^2+b^2=c^2)
43^2+81^2=93^2
1849 + 6561 = 8649
8410 =/= 8649
Because the sides do not equal each other, this is not a right triangle.
