Given : 2,0), (5,0), (6,2) एवं (3,2) स्थानांक वाले बिन्दुओं को क्रम से मिलाने पर एक चतुर्भुज
To Find : प्रमाणित करो कि समानान्तर चतुर्भुज प्राप्त होता है
Solution:
A = (2 , 0)
B = ( 5 , 0)
C = ( 6 , 2)
D = ( 3 , 2)
AB Slope = (0 - 0)/(5 -2 ) = 0/3 = 0
CD Slope = (2 - 2)/(3 - 6) = 0/-3 = 0
=> AB || CD
BC slope = (2 - 0)/(6 - 5) = 2
AD slope = (2 - 0)/(3 - 2) = 2
=> AD || BC
AB = 3
CD = 3
BC = √(2-0)² + (6 - 5)² = √5
AD = √(3-2)² + (2 - 0)² = √5
AB = CD , AB || CD
BC = AD , BC || AD
ABCD समानान्तर चतुर्भुज
