This is awesome - kids can slap up post-it style thoughts, links, pics and vids... we could make contributing to this a homework task, and they will all see what the others are thinking when they do it....

But if the angles dont have to be together, how do you know they are 90 degrees?

Next week you will have an awesome activity, Maurice.

# data[].attributes.body
Almost. Ran out of time... (finish it together on the weekend?)

# data[].attributes.body
Did anyone finish that sheet today?

LOL FRANK U R SO FUNNY LOLZ.

For reals though, I want to know how we actually use complementary angles in the real world.

# data[].attributes.body
I payed my angle a complement.

# data[].attributes.body
Yeah me too. My thirst for knowledge is insatiable! Next topic please!

# data[].attributes.body
I'm feeling confident with this topic. Ready to move on.

Yeah this guy is lame. Look at Larry's link. Khan Academy rocks!

Imagine designing a building like this - I suppose angles ARE important :P :P :P

# data[].attributes.body
Here's a quick video of this guy talking about angles. I still dont get it though

# data[].attributes.body
Found this: it really helped!

Learn about complementary and supplementary angles, as well as the definitions of adjacent and straight angles.

Coz if you dont know an angle, but its complementary to an angle you DO know, then you can work it out ^.^

Like the activity we did in class

# data[].attributes.body
Yeah but what I dont get is why we need to know this?

Giles: So if two angles add up to 90 degrees, they are called "complementary"...
