Classifying angles as acute (< 90°), right (= 90°), obtuse (90°-180°), straight (= 180°), or reflex (> 180°).
Where your child meets this in real life: Describing angles in everyday objects, navigation, or sports
Each SEAG paper has 28 maths questions. Questions 29 to 50 are multiple choice with five possible answers, and questions 51 to 56 need a short written answer. With 56 questions in 60 minutes across English and maths, that is about a minute per question.
SEAGReady breaks classify angles into 3 steps, taught in order so each skill builds on the last.
Identify right angles (90°) as the 'corner' or 'L-shape' angle that forms a square corner
Classify angles as acute (less than 90°) or obtuse (between 90° and 180°) by comparing to a right angle
Recognise straight angles (exactly 180°) and reflex angles (between 180° and 360°)
Try three free questions from our classify angles course. They start easy and get harder, so you can see where your child's confidence runs out. If they manage the last one without a hint, this topic is probably secure. If not, the steps above show where to start.
Leah looks at the square-corner angle shown. Is it a right angle?
Ronan looks at the 35-degree angle shown. What type of angle is it?
Jamie has five angles: 85 degrees, 180 degrees, 200 degrees, 95 degrees, and 310 degrees. How many of these are reflex angles?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Charlotte is looking at different corners in her classroom to find right angles.
Is the corner of her maths textbook a right angle?
90°
A right angle is exactly 90 degrees
Step 1 of 4
Charlotte is looking at different corners in her classroom to find right angles.
Is the corner of her maths textbook a right angle?
Yes, the corner of the textbook is a right angle (90 degrees).
The key insight: Right angles appear everywhere - look for the square corner 'L' shape!
Common mix-up: Thinking right angles only appear in squares and rectangles. Right angles appear in many places - book corners, door frames, even some triangles.
These are the misconceptions we see most often in classify angles, including the ones our practice questions are specifically designed to catch.
Struggling with classify angles? The real gap is often in one of these earlier topics.
