Which angle opens the least?
Look at the space between the two arms, not the direction they point.
Each angle is turned to start from the same horizontal line. Its opening stays the same.

Look past direction and arm length to compare how far two lines open.

How this data is usedHelp
Choose all four angles from smallest to largest. Tap a chosen angle to remove it, or use Undo and Reset order. Nothing is submitted until you press Check order.
After checking, compare the degree values. Align angles turns each figure to the same starting direction without changing its opening. Turn it off to see the original positions.
An angle measures the opening between two arms. Turning the whole figure does not change that opening. All arms here have the same length.
Each completely correct order earns one point. Finish all five questions to save a result on this browser. There is no time limit or speed bonus.
Use Tab and Enter or Space to select figures. Keys A–D also select a figure. This is a visual practice; the figures require sight. These original questions are not an official exam or an intelligence assessment.
About this practice
Choose the four angles from the smallest opening to the largest, then select Check order. The opening between the arms is what matters. Turning an angle changes where it points, but leaves its size unchanged. There is no time limit.
A worked order
Use a square corner as a 90° reference. First separate narrower openings from wider ones, then compare the angles within each group. Imagine turning one arm of each angle to the same starting direction.
Standard difficulty. Put these openings in order.
- Sort them against a square corner first. Sharper: A and D. Close to square: B. Wider: C.
- Then compare inside each group. D opens wider than A.
- Smallest to largest: A, D, B and C.
The same angles aligned, with the answer revealed
A → D → B → C is the complete order. B is close to a square corner, but its 91° opening is still larger than D’s 78°. Pointing upward or looking steeper does not make an opening larger.
What difficulty changes
Each question uses four distinct openings with equal arm lengths. The gap between neighbouring angles in the correct order is 18–28° on Easy, 10–16° on Standard, and 5–9° on Challenge. Smaller gaps make nearby openings harder to separate; they do not change the ordering rule.
What your result means
A completed round contains 5 questions. Each fully correct order earns one point. One swapped pair makes that question incorrect, even if the other positions are right. You can edit your selection before Check order; after checking, use Align angles to compare the openings from a common starting direction.
The result shows correct orders and active time. There is no speed bonus. Compare completed rounds at the same difficulty, and look for which neighbouring pair you reversed. An early finish shows the questions checked so far and is not saved as a completed round.
