When you first enter the Manor Parlour and watch the FMV scene where Claudia runs away. The late Baron’s nephew, Simon, will be available to talk to. Speak with him and he will challenge you with puzzle 011 – Arc and Line.

How many picarats is Puzzle 011 worth?

Puzzle 011 is worth 20 picarats.

How to solve Puzzle 011?

For puzzle 011, you need to work out the length of a line within a rectangle, using the details provided in the puzzle and the external quarter-circle shape.

Professor Layton and the Curious Village puzzle 011 - Arc and Line Description

As shown in the diagram below, you have one-fourth of a circle. Within this circle is rectangle ABCD, which touches the edge of the circle at point D.

Assuming that point B is located at the center of the circle, how long is diagonal line AC.

While at first glance, this may seem like a difficult puzzle, it’s worth noting that it’s only worth 20 picarats – an indicator of its true difficulty.

Therefore, assume that there is some trick involved which means you won’t need to worry about using mathematical equations to get the answer.

The position of point D is important in finding the answer.

What are the hints for Puzzle 011?

Hint 1

Professor Layton and the Curious Village puzzle 011 - Arc and Line Hint 1

Surely somebody must have looked at the diagram and realized that the triangle formed by points A, B, and C is a right triangle.

That’s sharp thinking and exactly right. However, are you sure there isn’t a much easier way to find the answer?

Hint 2

You don’t need the Pythagorean theorem to answer this one. Something else in the diagram should be the exact same length as AC.

Hint 3

Professor Layton and the Curious Village puzzle 011 - Arc and Line Hint 3

Notice that diagonal line AC within the rectangle is the same size as the diagonal line BD.

Have you also noticed that BD is also the same length as another part of this diagram?

Puzzle 011 Answer

The length of line AC is 10 inches.

The shape is a quarter of a circle.

Therefore, because line AC is the same length as line BD, it’s also the same length as the radius of the complete circle – which the puzzle hands you.

It might have been difficult to notice because the puzzle makes you focus on line AC, but as soon as you acknowledge line BD (and you remember your geometry), this puzzle is as good as solved.
