A 3×3 matrix has circles in row 1, squares in row 2, and triangles in row 3. Each row has small, medium, and large shapes. What shape fills the bottom-right cell?

Answer: Large triangle

Row 3 has triangles; the bottom-right corner must be the large triangle to complete the size sequence.

Each figure in a series gains one extra side: triangle, square, pentagon, ___.

Answer: Hexagon

Triangle (3 sides), square (4), pentagon (5), so the next is hexagon (6 sides).

A shape is reflected across a vertical axis. If the original has a star in the top-right, where is the star after reflection?

Answer: Top-left

Reflecting across a vertical axis swaps left and right, moving the star from top-right to top-left.

In a number matrix, row 1 = [2, 4, 8], row 2 = [3, 6, 12]. What is the missing value in row 3 = [5, 10, ___]?

Answer: 20

Each row doubles its values: 5 × 4 = 20, or 10 × 2 = 20.

A figure is rotated 180°. An arrow originally pointing up now points ___.

Answer: Down

A 180° rotation reverses direction, so an upward arrow now points down.

Which piece completes the puzzle if the missing segment is the top-right of a 4-piece square divided diagonally?

Answer: A triangle pointing up-right

Dividing a square diagonally from bottom-left to top-right gives a triangle whose hypotenuse faces the top-right.
