A flat shape is folded along a dashed center line so that the left half lands exactly on the right half. The result is a shape half the width of the original. If the original was a rectangle 8 cm wide and 5 cm tall, what are the dimensions of the folded shape?

Answer: 4 cm wide and 5 cm tall

Folding along the vertical center halves the width (8÷2=4 cm) while the height stays the same at 5 cm.

Shape A has a dot at its leftmost point. Shape B has a dot at its topmost point. In the correctly assembled figure, the leftmost point of A is connected to the topmost point of B. Where does Shape B appear relative to Shape A?

Answer: To the left of Shape A, with B's top touching A's left

For A's leftmost point to meet B's topmost point, B must be positioned to the left of A so B's top edge reaches A's left point.

A hexagon is divided into 6 equilateral triangles. If you remove one triangle and reconnect the remaining 5, what is the minimum number of sides the new shape can have?

Answer: 5

Removing one triangle from a regular hexagon creates a 5-sided (pentagon) indentation, yielding a shape with 5 outer sides at minimum.

Two L-shaped pieces are mirror images of each other. When placed together correctly, what shape do they most likely form?

Answer: A rectangle

Mirror-image L-shapes interlock to fill each other's missing corner, forming a complete rectangle.

A dot is placed at the midpoint of the top side of a square. A second shape's dot is at its bottom-right corner. In the assembled figure, these dots are connected. Where is the second shape?

Answer: To the upper-right of the square, with its bottom-right corner touching the square's top midpoint

The second shape's bottom-right corner must land at the square's top midpoint, placing the second shape to the upper-right.

A trapezoid and a triangle are the only two pieces of a puzzle. The triangle's base equals the trapezoid's shorter parallel side. Where does the triangle attach to complete a larger triangle overall?

Answer: On top of the trapezoid's shorter side, apex pointing up

Placing the triangle's base on the trapezoid's shorter top side, with the apex pointing upward, completes a larger triangle.

A puzzle piece has a straight top, a jagged right side, a curved bottom, and a flat left side. Which answer correctly identifies what adjacent pieces must look like?

Answer: The piece to its right has a jagged left side; the piece below has a curved top

Adjacent pieces must have complementary edges — the right neighbor needs a jagged left side to match, and the bottom neighbor needs a curved top to match.
