Verify that quadrilateral BCDE is a rhombus with vertices B(-5, 1), C(0, 6), D(5, 1) and E (0, -4) by showing that all four side
s are equal.
1 answer:
Find the distance between each
between points (x1,y1) and (x2,y2)
D=

find and verify that
BC=CD=DE=EB
so
BC=

=5√2
CD=

=5√2
DE=

=5√2
EB=

=5√2
true
