About Angles in Triangles and Polygons
GoConqr OriginalStart with the mind map
The Angles mind map is a useful starting point for seeing the topic as a whole. It brings together types of angles and triangles, including acute, right and obtuse angles, as well as equilateral, isosceles, right-angle and scalene triangles. It also includes the angle sum of a triangle.
Look over the categories, then use the map to check which terms you can explain without looking. This gives you a starting point for choosing flashcards and quiz questions.
Practice facts with flashcards
Angle Facts and Polygons asks about angle sums in triangles and quadrilaterals, angles around a point and on a straight line, and the meaning of a polygon. Use it to practice recalling facts before applying them to a missing-angle question.
Other flashcards cover angle types, triangle types and interior angles in polygons. A deck on exterior angles includes a definition and the exterior angle theorem. Students can work through the prompts and return to the mind map when they want to check a term or relationship.
Try a quiz and check your understanding
A listed quiz asks about finding a missing angle in a triangle when the other angles are given. After reviewing the triangle material, try that question and use the mind map or flashcards to revisit the angle fact involved.
Working between a quiz and the recall resources can help you identify which facts you want to study again. Teachers can also use the different formats to select material for angle-fact practice.
Explore the unit
This topic is part of Angles and Parallel Lines in Mathematics. The listed notes connect missing angles in triangles and polygon angles with angles on a straight line, angles at a point, and alternate and corresponding angles.

Frequently asked questions
Where should I start on this page?
The Angles mind map is a useful place to start because it groups angle types and triangle types together. Follow it with Angle Facts and Polygons to practice recalling angle sums and definitions. A listed quiz then gives you a missing-angle question to work through.
What does the mind map cover?
The Angles mind map brings together types of angles and triangles. It includes acute, right and obtuse angles, along with equilateral, isosceles, right-angle and scalene triangles. It also includes the angle sum of a triangle, making it a useful reference alongside the flashcards and quiz.
Are these resources free to use?
Yes. Every resource listed on this page is free to open, study and take without an account. A free account can also save your quiz scores and lets you make your own quizzes, mind maps, flashcards and notes. The listed resources were made by GoConqr users.
