This fast-progressing worksheet takes students through a range of angles in triangle problems and will suit a variety of learners and year groups.
In section A, learners will calculate the missing angles in triangles where two angles are known and in isosceles triangles where either one base angle or the top angle is known and in an equilateral triangle.
Section B consists of multi-step problems, including external and vertically opposite angles and triangles within triangles. Challenge your students with an extension question that will present them with an isosceles triangle within a pentagon and introduce the concept of interior and exterior angles of regular polygons.
