Maths assesment

I can apply the strategy to problem solving questions

Strategy: Deduce the angle properties of intersecting and parallel lines and the angle properties of polygons and apply these properties.

Take a piece of paper.

Fold it along the long axis and then open it up.

Now fold one corner over and onto the centre crease so that the fold line passes through the corner next to it (on the short side of the paper).

You have created some angles. There are angles of 60o and of 30o. Can you prove this? Explain your answer

Because a triangle is 180 degrees there is already 90 degrees in the triangle there must be 60 degrees and 30 degrees and add that together makes 90 degrees and 90 degrees + 90 degrees equals 180 degrees.
