Angles in triangle worksheet

Overall rating 3 out of 53.7 (22 ratings)

Last updated 14 March 2014, created 15 May 2011, viewed 62,440

Worksheet for pupils to find the missing internal angle of triangles, when 2 of the angles are given. The angles are NOT accurately measured! If this were the case then the worksheet would be useful in teaching pupils how to measure angles. Rather, the worksheet is designed to teach pupils that t More…he internal angles of a triangle equal 180 degrees, and how to use that knowledge to find a missing angle.

A good resource that was easily amended to fit the children's needs. A good level of challenge for the children, making them apply their knowledge of angles on straight line etc.

Really helpful thanks for sharing. Good for getting the children to begin applying their knowledge. I adaped slightly by moving labelled angles inside triangles so as not to confuse them.

I don't understand the couple of negative comments. The 1 rating by the person who made the point about the angles not measuring correctly, should not even count towards the resource's rating as they have missed the point of the resource. The resource is easy to use and follow and a great time saver. Many thanks!
