The Problem
Your teacher has requested a list of objects which have particular angles in them. Your challenge is to decipher the angles using your knowledge of angles, fractions and 2D shapes.
First watch this video.
First watch this video.
You may need to watch this a few more times and you may like to create your own angle-a-tron to help you find the angles your teacher needs.
Next, record the angles your teacher wants you to find - you need to record what your teacher has written and then convert it into the number of degrees and decide if it is right angled, acute or obtuse. (HINT: Use the strategy - Draw a Table).
This video will help you know which angle is which.

Here are the angles your teacher is looking for. Record the angle and it's type.
Next, you need to collect a list of items which have the angles your teacher is looking for. the items may have more than one angle. You need to decide the best way of recording this information. You may need your angle-a-tron to help you find the angles.
