Where is the Maths?

Always an equal distance apart! Parallel Lines Parallel Lines Always an equal distance apart! Will never meet

Ext: Prove the angles in a triangle add to 1800 Find Equal Angles! Draw a ‘cartoon strip’ of four diagrams to show the same thing Ext: Prove the angles in a triangle add to 1800
