highlight%28cross%28Th%29%29 The base of an isosceles triangle is 2 root2 cm.
If the medians to the equal sides intersect at right highlight%28cross%28angles%29%29 angle, then the height of the triangle, in cm, is
~~~~~~~~~~~~~~~~~~~~~~


The two intersecting medians and the base of the given triangle form an isosceles right triangle with the hypotenuse of 2%2Asqrt%282%29 centimeters.


Hence, the altitude of this isosceles right triangle drawn to its hypotenuse is exactly HALF of the base, i.e. sqrt%282%29 centimeters.


Next, the length of this altitude is exactly one third of the height of the given triangle; 

so, the height of the given isosceles triangle is 3%2Asqrt%282%29 centimeters.    ANSWER


Solved.

In this version those deficiencies are fixed, which is GOOD.
