Angles in Triangles (A) WORKSHEET DESCRIPTION
This worksheet will help students practise calculating missing angles in triangles using the angle sum rule.
Section A begins with a guided example, and bar models are used throughout to support calculations.
Section B asks learners to decide whether triangles are feasible or not based on their angle sum, providing a selection of both examples and non-examples.
In Section C, pupils tackle ten minimally different questions that build reasoning skills step by step. Finally, =
Section D extends the practice with a wider variety of angle problems, including those where angles are expressed in ratio.
