Answer : 2

Explanatory Answer

In-radius of the triangle= (a+b-h)/2, where a and b are the lengths of two legs of the triangle and h is the hypotenuse.
In-radius= (8+6-10)/2= 4/2= 2 units


The question is "The coordinates of the three vertices of a triangle are: (1, 2), (7, 2), and (1, 10). Then the radius of the incircle of the triangle is"

Hence, the answer is '2'
