Learning Objectives
Grade F
To be able to demonstrate how to draw and measure angles accurately.
Can you explain in simple steps how to use use a protractor?
To recall that the sum of the angles on a line is 180o and the sum of the angles at a point is 360o and to use this knowledge to investigate angle puzzles.
If there are 5 equal angles around a point, can you work out the angles?

Learning objective for next lesson:
Grade F
To investigate and then remember that the angles in a triangle add to
180o.
How do we know that the angles in an equilateral triangle will always be
60o?
Grade E
To investigate and then remember that the sum of the angles in a
quadrilateral is 360o.
How can you show that the angles in a quadrilateral always add to
360o?
