Hello.
It's a brand new term and it's time to learn some brand new things. On
Monday we had a powhiri for our new Japanese teacher and a teacher who
will be going into room 6 while Mrs Davidson is on maternity leave. A
powhiri is a Maori formal welcome. All the year 7s were welcomed in one
on the first day of school this year. I also learnt how to find out
missing angles of a polygon. If you had a 5 sided shape (pictured below) 
and you knew these
angles: A-190° B-70° C-130° D-120°
E-? Therefore you need to find out E. A + B + C + D (190 + 70 +130 +
120) = 510, this is answer A, now count the sides. There are 5. You take
away 2 from 5 to get the amount of triangles. That would be 3. Now
multiply that number by 180. That is 540, this is answer B. Now take
answer A away from B. That is 30, so E must be 30°. You can do this with any polygon. A regular polygon is slightly faster. Lets try it with an octagon.
If you new none of these angles, but they were all the same you would just have to count the sides =8. On Tuesday morning I did Tech art, I think my truck is going well but I definitely need to get a move on, as we only have two more lessons. We also had a visitor called Mike King who told us about depression and his addiction to alcohol and drugs.
