Glven: A(0,6), B(6,6), C(6.0), D(0,0); ZDAB, ZABC, ZBCD, LCDA are right angles.
Prove: ABCD is a square.
DA square on a coordinate plane
Proof:
.
AB = V (22 β 32)2 + (y2 β 1)? so AB =
.
β’ BC =
(22 β 22) + (92 - y.) so BC =
β’ CD= V(302 - 31) + (92 - 1)? So CD =
β’ DA= V(22 β 21)2 + (92 - y1) so DA =
.
Since ABCD has four
angles and four
sides, it is a square.
