Plzzz with five and six i will try not to bother you any more look and go away

#5 is not an isosceles or equilateral because all the side measurements are different. So it is a scalene, and it has an angle that is more than 90 which also makes it obtuse. 
#6 is also scalene, but because all the angle measurements are smaller than 90, it is acute.

The answer is 26 to 1
