数顶点 = kira bucu 用手指从一个顶点开始，沿着边走一圈，每到一个角就数一个，回到起点就停。这个图形一共有 6 个顶点，所以它是正六边形 heksagon，也有 6 条边。 例子：正五边形走一圈会数到 5 个角。 注意：回到起点那个角不要再数一次，否则会多出 1 个。

counting vertices = kira bucu Put your finger on one corner and trace round the edges, counting each corner you reach, and stop when you are back at the start. This shape has 6 vertices, so it is a regular heksagon with 6 sides as well. Example: going round a regular pentagon you count 5 corners. Watch out: do not count the starting corner again at the end, or you will get one too many.

拼写名称 = eja nama 八边形的马来文是 OKTAGON，读成 ok-ta-gon。空格在 T 和 G 之间，要填字母 A。填 E 就变成 oktegon，填 O 就变成 oktogon，都不是正确的写法。 例子：PENTAGON、HEKSAGON、HEPTAGON 也都是 “-agon” 结尾。 注意：这些名称的结尾都是 a-g-o-n。

spelling the name = eja nama The Malay word for an eight-sided polygon is OKTAGON, said ok-ta-gon. The gap sits between T and G, so the missing letter is A. Writing E gives oktegon and O gives oktogon, which are both wrong spellings. Example: PENTAGON, HEKSAGON and HEPTAGON also end in “-agon”. Watch out: every one of these names ends with the letters a-g-o-n.

判断叙述 = pilih pernyataan betul 正多边形的三个重点：每条边都是直的；每条边都一样长；边数等于顶点数。所以“所有边一样长”是对的。“有一条弯边”错，因为正多边形没有弯边；“顶点比边多”也错，两者一样多。 例子：正方形 4 条边、4 个顶点，每边一样长。 注意：读题时留意题目问的是“betul”（对的）还是“salah”（错的）。

choosing the true statement = pilih pernyataan betul A regular polygon has three key features: every side is straight, every side is the same length, and the number of sides equals the number of vertices. So “all sides are equal” is true. “It has a curved side” is false, and “more vertices than sides” is false because they are equal. Example: a square has 4 sides, 4 vertices and all sides equal. Watch out: check whether the question asks for the true (betul) or the false (salah) statement.

找正多边形 = cari poligon sekata P 是正方形，4 条边一样长，是正多边形。Q 是平行四边形，上下边比斜边长；R 是梯形，上边短、下边长。Q 和 R 的边都不一样长，所以都不是正多边形。 例子：正方形的瓷砖每边都一样长。 注意：只看“有 4 条边”是不够的，还要比较每条边的长短。

finding the regular polygon = cari poligon sekata P is a square with 4 equal sides, so it is regular. Q is a parallelogram whose top and bottom are longer than its slanted sides, and R is a trapezium with a short top and a long bottom. Q and R do not have equal sides, so they are not regular. Example: a square floor tile has four equal sides. Watch out: having 4 sides is not enough; you must also compare the lengths of the sides.

七条边 = 7 sisi 7 条边的正多边形叫 heptagon（七边形）。heksagon 是 6 条边，oktagon 是 8 条边，正好在 7 的两边，所以最容易选错。记住 hep-t-agon 的 t 像 tujuh。 例子：heptagon 有 7 条边和 7 个顶点。 注意：heksagon（6）和 heptagon（7）只差两个字母。

seven sides = 7 sisi A regular polygon with 7 sides is called a heptagon. The heksagon has 6 sides and the oktagon has 8, one on each side of 7, which is why they are the easiest wrong choices. Remember the t in hep-t-agon as in tujuh. Example: a heptagon has 7 sides and 7 vertices. Watch out: heksagon (6) and heptagon (7) differ by only two letters.

完成特征表 = lengkapkan jadual oktagon 是八边形，有 8 条边。正多边形的边数和顶点数一样多，所以顶点也是 8 个。答案是 8 条边、8 个顶点。另外两个选项边和顶点不一样多，一看就不对。 例子：pentagon → 5 条边、5 个顶点。 注意：填表时边和顶点那两格的数字应该相同。

completing the table = lengkapkan jadual An oktagon is an eight-sided polygon, so it has 8 sides. A polygon always has as many vertices as sides, so it also has 8 vertices. The answer is 8 sides and 8 vertices. The other two choices have different numbers of sides and vertices, so they cannot be right. Example: a pentagon has 5 sides and 5 vertices. Watch out: in the table, the side and vertex columns should hold the same number.

比五边形多两个顶点 = 2 bucu lebih daripada pentagon 五边形有 5 个顶点，多 2 个就是 5 + 2 = 7 个顶点。7 个顶点就有 7 条边，名字是 heptagon。选 heksagon 是只加了 1；选 oktagon 是加了 3。 例子：比正方形多 2 条边 → 4 + 2 = 6 → heksagon。 注意：“lebih” 是多出来，要用加法。

two more vertices than a pentagon = 2 bucu lebih daripada pentagon A pentagon has 5 vertices, and 2 more makes 5 + 2 = 7 vertices. Seven vertices means 7 sides, and that shape is a heptagon. Choosing heksagon adds only 1, and choosing oktagon adds 3. Example: 2 more sides than a square gives 4 + 2 = 6, a heksagon. Watch out: “lebih” means more, so you add.

边数相加 = jumlah sisi 五边形有 5 条边，八边形有 8 条边，合起来是 5 + 8 = 13 条边。选 12 或 14 是把其中一个的边数记错了，例如把八边形当成 7 条或 9 条。 例子：一个六边形和一个七边形，边数一共 6 + 7 = 13。 注意：先写出每个图形的边数，再相加。

adding sides = jumlah sisi A pentagon has 5 sides and an octagon has 8 sides, so together they have 5 + 8 = 13 sides. Choosing 12 or 14 means one of the side counts was remembered wrongly, for example treating the octagon as having 7 or 9 sides. Example: a heksagon and a heptagon together have 6 + 7 = 13 sides. Watch out: write down each shape's number of sides first, then add them.
