Angles
Angles in a triangle Let’s Learn Together Riana cuts out a triangle. She colours each angle a different colour.
She rips her triangle into three pieces and puts the angles together.
Riana notices that all the angles make a straight line.
This means the angles in a triangle must add up to 180°
My angles make a straight line! I remember that angles on a straight line always add up to 180°.
