In 8th Grade, students are expected to understand and apply the triangle theorem to solve a different kind of problem. “Find missing angle Quiz” consist of several questions where the students are asked to find the missing angle of the given triangle by using the properties and theorems of the triangles.

To solve this quiz, student should have the knowledge of angle sum property of a triangle, according to this property, the sum of all interior angles of a triangle is 180°. Using this quiz, teachers can easily identify the knowledge gaps of the students and help them to understand the properties of triangles.
