In ΔABC, if is a right angle, then
a2= b2+c2
b2= c2+a2
c2= a2+b2
a2>b2+c2
If ΔABC is similar to ΔDEF ; then DF=
4.5
3.5

If two triangles are congruent, they have
the same shape
the same size
the same size and the same shape
no similarity
ΔABC ~ΔPQR; If AB = 6; BC = 4; AC = 8 and PR = 6; then PQ + QR =
7.5

Given MN|| BC; ΔABC and ΔANM are
Non -similar
Congruent
Equal in area
Similar
If Δ ABC is similar to ΔDEF; then EF=

In ΔABC, if then
b2= a2+c2
b2> a2+c2
b2< a2+c2
a2> b2+c2
From the above figure, x=
