Question

Plz give Full Solution:)

Answer 1

Please Help^_^

Answer 2

for abcd is a Parallelogram
connect XC, so AX=0.5DC
the angle AXD=CDX & AMX=DMC & XAC=DCA
we can say that triangle AXM is similar to triangle CDM and AXM is half of CDM
so AM=0.5MC=AC/3
in the same way, we can work out CN=0.5AN=AC/3
SO MN is 1/3 of AC
AC=4.5cm
MN=1.5cm

@UnkleRhaukus @Calcmathlete Plz help:)

Answer 7

Um. I can't really help with this unless you know similarity. There might be a way involving only congruence, but I can't really explain it any other way. Just know that if 3 angles are congruent to three angles in another triangle in the same order, then they are similar by the AA Similarity Postulate. Similar triangles have proportional side lengths.

Why don't you give it a shot @UnkleRhaukus ? I gotta go...
