Remember: Count the angles. Three is a triangle, four is a quadrilateral, five is a pentagon and six is a hexagon.

Tilted shapes

3
How many angles does this turned shape have?
4
A square and a rectangle are both quadrilaterals.
TrueFalse

Count and compare

Count the angles. Turning a shape does not change them.

Answer key · Set C
Naming shapes, counting corners: a step further
1quadrilateral Count four angles. Four angles make a quadrilateral, however it is tilted.
2hexagon Count six angles. Six angles make a hexagon.
33 Count each corner once: 1, 2, 3.
4True Each has 4 angles, and any shape with 4 angles is a quadrilateral.
57 The triangle has 3 angles and the square has 4. 3 and 4 make 7.
61 The pentagon has 5 angles and the hexagon has 6. 6 take away 5 is 1.
7hexagon A pentagon has 5 angles. One more is 6, which is a hexagon.
8False A hexagon has 6 angles and a pentagon has 5. A hexagon has more.
94 6 faces take away 2 blue ones leaves 4.
101-B, 2-A, 3-C Triangle 3, quadrilateral 4, pentagon 5, hexagon 6. Each has one more than the one before.
11A, C The hexagon has 6 angles and the pentagon has 5. The triangle has 3 and the rhombus has 4.
