ABC is a triangle. AD is a median of ABC. E is the midpoint of AD and produced to meet AC at F. prove that AF=1/3AC
what is the full form of cpct ? what does it mean ?
If we can prove SAS congruence by this method, why can't we prove ASA congruence by this ?We can take two triangles ABC and DEF with angle A = angle D, angle B = angle E and side AB = DE ..!
Then we can simply put triangle DEF over triangle ABC and we'll see that all its corresponding parts will coincide which indeed proves that both the triangles are congruent. Thus equal in area.I just want to know why can't we prove ASA congruence by this method ?Please answer it as soon as possible.
