Frequently asked questions
- What's on a Grade 8 angles worksheet?
- Each pack has up to 12 questions per page with a matching answer key, tuned to Grade 8, with beginner, intermediate, and advanced options so you can match the child's level.
- How do you classify an angle?
- Acute is less than 90°, right is exactly 90°, obtuse is between 90° and 180°, and straight is exactly 180°.
- What are complementary and supplementary angles?
- Complementary angles add to 90°; supplementary angles add to 180°.
- What do the angles of a triangle add up to?
- Always 180°, so a missing angle is 180° minus the other two.
