Question 1

In a series, each shape is divided into one more equal part than the previous. Shape 1 is undivided, shape 2 is halved. How many parts does shape 5 have?

Accepted Answer

5

Answer

Shape 1=1 part, shape 2=2 parts, shape 3=3, shape 4=4, shape 5=5 parts.

Question 2

Three figures form a group: pentagon, hexagon, heptagon. A second group starts with a square. Applying the same +1-side progression, what is the third figure in the second group?

Accepted Answer

Hexagon

Answer

Square (4) → pentagon (5) → hexagon (6), so the third figure is a hexagon.

Question 3

A figure is reflected vertically (top-bottom flip) then rotated 180°. Compared to the original, what is the net transformation?

Accepted Answer

Horizontal reflection only

Answer

A vertical flip followed by a 180° rotation is equivalent to a horizontal reflection.

Question 4

In a pattern, small shapes are inside large shapes. The rule is: the number of small shapes inside = number of sides of the large shape minus 2. A large pentagon contains how many small shapes?

Accepted Answer

3

Answer

Pentagon has 5 sides; 5 − 2 = 3, so there are 3 small shapes inside.

Question 5

A sequence of figures grows by adding one shape to the right at each step. Step 1 = one circle, step 2 = circle-square, step 3 = circle-square-triangle. Step 4 adds which shape if the pattern cycles back to circle?

Accepted Answer

Circle

Answer

The shapes cycle: circle, square, triangle, circle, so step 4 adds a circle.
