Three worksheets on complementary angles, supplementary angles, and vertical angles. They includes introductory notes with the definitions of these types of angles. The exercises require to identify complementary, supplementary and vertical angles, find the complementary and supplementary angles of a given angle and write and solve equations to find missing complementary and supplementary angles, as well as angles on a line and angles in a circle. It includes harder exercises on this topic. Detailed solutions are included.

A collection of seven worksheets on the following topics: Classifying Triangles. There is a worksheet on classifying triangles by their sides, a worksheet on classifying triangles by their angles and a worksheet on classifying triangles by their sides and angles. The students are given some triangles to classify and in some cases they are required to find missing angles of the triangles (using the triangle angle sum theorem). In addition they are given some other exercises (true/false, blanks to complete) in order to test their knowledge on the different types of triangles. Triangle Angle Sum Theorem. There is a worksheet on the triangle angle sum theorem. The exercises require to find missing angles by using the triangle angle sum theorem and the properties of special types of triangles (isosceles and equilateral). Exterior Angle Theorem. There is a worksheet on the triangle exterior angle theorem. The exercises require to find missing angles by using the triangle exterior angle theorem. Triangle Angle Sum Theorem and Exterior Angle Theorem. There is a worksheet on the triangle angle theorem and triangle exterior angle theorem. The exercises require to find missing angles by using the two theorems. Parallel Lines Cut by A Transversal. There is a worksheet to help students strengthen their skills in the concept of parallel lines cut by a transversal. The following angle relationships occur in the exercises: complementary angles, supplementary angles, vertical angles, alternate interior angles, alternate exterior angles, consecutive interior angles and corresponding angles. In the first two exercises, students are given a diagram with two parallel lines cut by a transversal and are required to identify the relationships between some given pairs of angles. In the next exercises, students are given some diagrams with missing angles which are required to find by using their knowledge on the topic. Elementary and harder exercises are included. Detailed solutions are included.
