Pythagorean Theorem & LEGO

What was the initial method demonstrated for attaching Lego pieces at an angle?

• Using specialized angled bricks.

• Employing a mathematical formula to calculate angles.

• Placing studs on the bottom of a plate/brick and finding a fit by trial and error.

• Utilizing flexible connectors.

What are the key characteristics of a Pythagorean Triple as described?

• All sides are prime numbers and there are two right angles.

• One right angle and all sides are whole numbers.

• All angles are equal and all sides are whole numbers.

• Two equal sides and one right angle.

When applying Pythagorean Triples to Lego, what is the correct way to measure the "length" of a side?

• By counting the number of studs on the brick.

• By counting the intervals between the studs.

• By measuring the physical length with a ruler.

• By estimating the length visually.

What is a practical application of using Pythagorean Triples for angled Lego structures?

• To create curved walls.

• To ensure structural stability by placing supporting studs at calculated points.

• To build perfectly circular designs.

• To connect pieces without any studs.

What are the approximate non-right angles of a right triangle constructed using the 3-4-5 Pythagorean triple?

• 22.6 degrees and 67.4 degrees

• 30 degrees and 60 degrees

• 36.87 degrees and 53.13 degrees

• 45 degrees and 45 degrees

When building a right triangle with LEGO using the 3-4-5 Pythagorean triple compared to the 5-12-13 triple, what is a notable difference in their construction?

• The 3-4-5 triple results in a larger triangle.

• The 5-12-13 triple results in a steeper angle.

• The 3-4-5 triple allows for more attachment points.

• The 5-12-13 triple is easier to scale up.

A right triangle with two equal sides and two equal non-right angles is known as what type of triangle?

• Equilateral triangle

• Scalene triangle

• Isosceles triangle

• Obtuse triangle

What side ratio is suggested for building an isosceles right triangle in LEGO that works "just about perfectly" according to the Pythagorean theorem?

• 3-4-5

• 5-12-13

• 12-12-18

• 10-24-26

Why did the speaker initially suggest that the 12, 12, 18 stud length combination might not be a true Pythagorean triple?

• The stud lengths were not perfectly divisible by three.

• The angle formed by the diagonal piece was not a perfect 90 degrees.

• The "stud length" unit of measurement does not consistently apply to diagonal distances.

• The pieces were too flexible to maintain their shape.

When a 9-long plate is used to form a diagonal, why does it not align perfectly with whole stud measurements?

• The plate is too short for the intended diagonal.

• The plate fits in a half-stud distance, not a whole stud.

• The plate is designed for vertical connections only.

• The studs on the plate are misaligned.
