Question

what is c.p.c.t. in triangle please explain it

Answer 1

corresponding part pf corresponding triangle
if any two triangles are congruent by sss congruence property
say like,
ab=pq
bc=qr
ac=pr
then the corresponding angle will same
angle between ab and bc = angle between pq and qr
the angle b/w ab abd bc would not be equal to angle b/t pq and pr.

Answer 2

c.p.c.t is a mathematical phenomena which means if two triangles are congruent then, each and every angle as well as side of those two triangles will be equal i.e. congruent
c.p.c.t exactly means "congruent parts of congruent triangles"......
I hope this will hell you friend
