Question

Ubahlah setiap titik berikut ke sudut rotasi 90°, 180° , -90°
a. P(13,28)
b. Q(19,-14)
c. R(-11,20)
d. S(-7,-15)

Answer 1

A) P (13,28) R 90°= P'(-28,13)
a) P (13,28) R 180°= P'(13,-28)
a) P (13,28) R -90°= P'(28,-13)

b) Q (19,-14) R 90°= Q'(14,19)
b) Q (19,-14) R 180°= Q'(19,14)
b) Q (19,-14) R -90°= Q'(-14,-19)

c) R (-11,20) R 90° = R'(-20,-11)
c) R (-11,20) R 180°=R'(-11,-20)
c) R (-11,20) R -90°=R'(20,11)

d) S (-7,-15) R 90°= S' (15,-7)
d) S (-7,-15) R 180°= S' (-7,15)
d) S (-7,-15) R -90°= S' (-15,7)
