Pattern Completion Flashcards

A 3x3 grid has shapes arranged so that each row contains a circle, square, and triangle. The top row has: circle, square, triangle. The middle row has: square, triangle, ___. What completes the pattern?

Answer: Circle

Each row must contain one circle, one square, and one triangle, so the missing shape is a circle.

In a pattern strip, figures alternate between filled and unfilled. The sequence shows: filled star, empty star, filled star, empty star, ___. What comes next?

Answer: Filled star

The pattern strictly alternates filled/empty, so after empty star the next must be a filled star.

A rectangular figure is divided into four quadrants. The top-left is shaded dark, top-right is white, bottom-left is white, and bottom-right is ___. The pattern follows diagonal symmetry.

Answer: Dark shaded

Diagonal symmetry means top-left and bottom-right share the same shading, so the bottom-right must be dark.

Each row in a matrix has shapes that increase in number: row 1 has 1 dot, row 2 has 2 dots, row 3 has 3 dots. The missing piece in row 3 should have how many dots in total?

Answer: 3

Row 3 follows the rule of having 3 dots, matching its row number.

A pattern shows shapes rotating 90° clockwise each step: arrow pointing up → arrow pointing right → arrow pointing down → ___. What is the next arrow direction?

Answer: Left

After pointing down, a 90° clockwise rotation produces an arrow pointing left.

In a 2x2 matrix, the top row shows a small triangle and a large triangle. The bottom row shows a small circle and ___. What piece is missing?

Answer: Large circle

The pattern scales the shape from small to large across each row, so a large circle completes the bottom row.

A border pattern around a rectangle uses: square corner → circle → square corner → circle. One circle is missing from the middle of the right side. What fills the gap?

Answer: Circle

The repeating unit is square corner–circle, so the gap between two corners on a side must be a circle.
