Answer:
Step-by-step explanation:
when a rotation of 180 ° happens, it switches the (x,y) coordinates from (x,y) to (-x,-y) .. that's alll... soo for M then, of (3,4) it switches to M ' = ( -3, -4) see?
Notice that the 2 expressions have 2 common terms.
(r-s) is just (s-r) times (-1)
similarly
(t-s) is just (s-t) times (-1)
this means that :
(r-s) (t-s) + (s-r) (s-t)=-(s-r)[-(s-t)]+(s-r) (s-t)
the 2 minuses in the first multiplication cancel each other so we have:
-(s-r)[-(s-t)]+(s-r) (s-t)=(s-r) (s-t)+(s-r) (s-t)=2(s-r) (s-t)
Answer:
