You can put this solution on YOUR website! I need to solve a proof for triangle ABC and DEC trying to prove C is the midpoint of AD. I am given that BC is equal to EC and angle A is equal to angle D
I'm sorry, but that is not true. Here is why:
Draw an isosceles triangle, label the two base angles A and D
Pick a point on the base of that isosceles triangle that is
obviously NOT its midpoint, and label it C.
With a compass, swing an arc with center C that cuts both legs of the
isosceles triangle. Label those two points where the arc cuts those legs
B and E
Draw radii BC and EC
Now in that figure we have triangles ABC and DEC
BC is equal to EC because
they are radii of the same arc.
Also angle A is equal to angle D because they are base
angles of an isosceles triangle.
But C is NOT the midpoint of AD!!!
So what you were asked to prove is just not true!!!
