Frequently asked questions

What's on a Grade 4 angles worksheet?
Each pack has up to 12 questions per page with a matching answer key, tuned to Grade 4, 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.
