If am=mb, then m is the midpoint of segment ab. true or false for logical reasoning (if-then statements) in geometry.

FALSE (in general)

Step-by-step explanation:

Consider an equilateral triangle T with vertices A, B and M.

Since T is a triangle, then A,B and M are not collinear (they are not in the same line).  

As T is equilateral, then AM =MB.

If M were the midpoint of AB, then M would lie on the same line that joins A and B, so A,B and M would be collinear, which is a contradiction.

So M cannot be the midpoint of AB.

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
