Calculating Angles in Triangles WORKSHEET
Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.
Calculating Angles in Triangles WORKSHEET DESCRIPTION
This fast progressing worksheet takes students through a whole range of angles in triangles 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, calculate missing angles in isosceles triangles where either one base angle or the top angle is known, and an equilateral triangle.
Section B consists of multi-step problems including the use of 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.
All worksheets are created by the team of experienced teachers at Cazoom Math.
