GAH! Math is so stupid! It doesn't make any sense!
Šmykľavka: 2
This protractor thing is impossible!
Šmykľavka: 4
Make sure the protractor is not backwards! It makes life so much easier if you can read the numbers.
Šmykľavka: 5
Before we measure, tell me if this is an acute, right, or obtuse angle.
Šmykľavka: 6
Acute?
It IS acute, so that means it measures less than 90 degrees. We already know the answer is between 0 and 90 degrees!
Šmykľavka: 7
There are two parts of the protractor to help you get the angle in the right place: 1) an upside-down T at the bottom middle 2) the base line (0 degrees or 180 degrees)
Šmykľavka: 8
We want to place the protractor on top of the angle so the middle of the T is at the vertex.
Šmykľavka: 9
Rotate the protractor so the vertex of the angle is still at the T, but one leg of the angle is lined up with the 0 degree line.
Šmykľavka: 10
The line doesn't reach the numbers!
That's OK. Don't you remember that definition about angles? Two RAYS with the same endpoint? Rays go on forever, so we can just extend the legs of the angle.
Šmykľavka: 11
The legs of the angle are extended, so we just need to read the numbers. Our options are 140 degrees or 40 degrees. Which is it?
Šmykľavka: 12
Acute angle! 40 degrees! Take that MATH!
Šmykľavka: 0
I will show you how to use it. Well, step 1...
Maybe I can help.
