Question

prove that in a pallelogram.1-the opposite sides are eqal.2-the opposite anges are eqal. and 3-diagonal bisect each other.​

Answer 1

Answer:

by cpct is is a palleogram

Step-by-step explanation:

draw the diagnoals now you have got 4 triangles

name them abo,cbo,cdo,dao

in triangle abo and cbo

ob = ob

angle b = angle b

angle o = angle o

hence it is congruent

ab =cb

in triangle cbo and cdo

oc = oc

angle c = angle c

angle o = angle o

hence it is congruent triangle cbo and cdo

cb=cd

by ab=cb and cb=cd

we get ab=cb

hence we know that in a palleogram parellal sides are equal

2 ) if abcd is a palleologram parrellal sides are equal

3) if abcd is a palleologram diagonal are equal
