If triangle MAS ≅ triangle TAR, the statement that could be false is letter B) segment MA ≅ segment SA. This can be false because these two congruent triangles can be 2 scalene triangles. So, segment MA can never be equal to segment SA. This can be true though, if and only if these triangles are isosceles triangles where 2 sides are equal. (See attached file to fully understand).
If triangle MAS ≅ triangle TAR. Which of the statements could be false? A) segment MA ≅ segment TA Eliminate B) segment MA ≅ segment SA C) ∠ ASM ≅ ∠ ART D) ∠ MAS ≅ ∠ TAR
