Year 5 Mathematicians- Investigating Angles

The last two days has seen Year 5 investigating angles. Do angles in a triangle have a relationship? Do angles in a quadrilateral have a relationship?

 

What we found out:

When you put the angles together (in a triangle ) they form a semi-circle like the protractor – Alan

It doesn’t matter what type of triangle it is, all the angles will add up to 180 degrees – Izzy W

I thought different quadrilaterals wouldn’t add up to 360 degrees because they have different types of angles but they all fit together to make a circle – Euron

 I thought (quadrilaterals) would add up to 360 degrees because a square does and different quadrilaterals are just a stretching square – Aimee.
