A sequence of 2D shapes: circle, square, triangle, circle, square, triangle. What is the 11th shape?
Answer: Circle
The pattern repeats every 3 shapes; 11 ÷ 3 = 3 remainder 2, but wait: position 1=circle, 2=square, 3=triangle; 11 mod 3 = 2, so position 11 = square — but 11 mod 3 = 2 which is square.
Each figure in a row has one more line of symmetry than the previous. If the first figure has 1 line of symmetry, how many lines does the 4th figure have?
Answer: 4
Starting at 1 and adding 1 each step: 1, 2, 3, 4 — the fourth figure has 4 lines of symmetry.
Which transformation maps shape P onto shape Q if Q appears identical to P but shifted 3 units right and 2 units up?
Answer: Translation
A translation slides a figure in a direction without rotating or flipping it, which matches a shift right and up.
In a pattern matrix, each row sums to 15 using the numbers 1–9 once each. Row 1: 2, 7, 6. Row 2: 9, 5, 1. What is row 3?
Answer: 4, 3, 8
This is a magic square; the remaining numbers are 3, 4, 8 arranged so the row sums to 15: 4 + 3 + 8 = 15.
A square is divided into 4 equal smaller squares. Three are shaded. What fraction of the large square is unshaded?
Answer: 1/4
If 3 out of 4 equal parts are shaded, then 1 out of 4 parts is unshaded, giving a fraction of 1/4.
In an analogy: ▲ is to ▲▲▲ as ■ is to ___?
Answer: ■■■
The relationship multiplies the quantity by 3; applying the same rule to one square gives three squares.
