Angles in Triangles (D) WORKSHEET
CCSSÂ Description: Understand that attributes belonging to a category of twoâdimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.
Angles in Triangles (D) WORKSHEET DESCRIPTION
This fast progressing worksheet takes students through a whole range of angles in triangles problems.
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.
