### We’ve enabled step-by-step help for this quiz

With bytelearn’s quizzes, your students receive targeted step-by-step help if they’re stuck or have questions, and you receive clear insights into their knowledge gaps.

Angles and geometrical shapes are both made of lines intersecting at specific points. Therefore, geometrical figures also have angles. Each shape has different angle properties to determine its angles. The Find Missing Angles (Simple Figures) Quiz tests students’ knowledge of calculating angles for different geometric shapes. This quiz also checks whether students understand the various properties of angles and other related concepts.
