Question 952664
The description does not work.  Either the triangle is isosceles, or equilateral, or scalene, or obtuse.  The description cannot agree with the legs being 9 unit each and base length also be 9 units for isosceles triangle.


If right angled isosceles triangle, then the two legs of 9 unit each must make the base side {{{9sqrt(2)}}}.  This forces the edge length of the square part to also be {{{9sqrt(2)}}} but they were given as 9 unit.
