Question 1210463
.
A straight line \ell divides a triangle \Delta into two congruent triangles.  Select all the statements that must be true.


(a) If Delta is isoceles, then it is equilateral

(b) If Delta is right, then it is equilateral

(c) \ell is parallel to a side of Delta

(d) \ell is longer than the midpoint of Delta
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



The statement (d) in the post makes no sense,


because "midpoint" has no length, and the conception of length is inapplicable to "midpoint".


You can not say "\ell is longer than the midpoint of Delta", because these words can not stay together in this connection.
