KS3 Maths Angles in a triangle animation

Overall rating 4 out of 54 (1 rating)

Powerpoint suitable for KS2 and KS3 Maths: Shape, space and Measure / Geometry - Triangle properties. This animation shows how angles in a triangle lie and a straight line and therefore add up to 180. I usually get students to test this out with their own card triangles and use this animations as a summary.

I like this as it shows clearly how and why the angles in a triangle add up to 180 degrees. You could get the pupils to do this with paper too. Nice to start off a lesson on angles showing this and starting a discussion.
