Raven's Progressive Matrices Line and Angle Patterns Flashcards

In a 3×3 RPM matrix, a horizontal line (0°) appears in the top-left cell, a line at 45° in the top-center, and a vertical line (90°) in the top-right. What is the angular increment per step?

Answer: 45°

The line rotates 45° clockwise with each step (0° → 45° → 90°), making 45° the angular increment.

A matrix row shows lines at 60°, 90°, and 120°. If the pattern continues in a fourth cell, what angle would appear?

Answer: 150°

The lines increase by 30° per step (60° → 90° → 120°), so the fourth cell would show 150°.

In an RPM problem, lines in each cell rotate 90° clockwise per column. If the first column shows a vertical line (90°), what does the third column show?

Answer: 180° (horizontal)

Two 90° clockwise rotations from 90° yields 270°, which is equivalent to a horizontal line at 180°.

Which of the following best describes a 'constant angle' pattern in Raven's Progressive Matrices?

Answer: All lines in the matrix share the same orientation

A constant angle pattern means every cell in the matrix contains a line at the same orientation, and no rotation occurs.

A matrix has lines at 0°, 45°, and 90° in column 1. Column 2 shows lines at 45°, 90°, and 135°. What rule governs this matrix?

Answer: Each column shifts all angles up by 45°

Every entry in column 2 is exactly 45° greater than the corresponding entry in column 1, indicating each column adds 45° to the set.

In an RPM figure, a line at 135° is described as pointing in which direction?

Answer: Diagonal from upper-right to lower-left

A 135° angle measured counterclockwise from horizontal produces a line slanting from upper-right to lower-left.

In a 3×3 RPM matrix, the angle of a line doubles each row (15°, 30°, 60°). Which concept does this represent?

Answer: Geometric angle progression

When each term is multiplied by a fixed factor (×2), the sequence is geometric rather than linear (additive).
