找对称轴三步 = tiga langkah mencari paksi simetri 第一步：把纸衣服从左往右对折，袖子对袖子、领口对领口，边缘完全对齐。第二步：打开，中间会留下一条折痕。第三步：把尺放在折痕上，用铅笔画一条直线，这就是衣服的对称轴。纸衣服只有这一条对称轴。 例子：对折后袖子没对齐，就要重新折一次。 注意：画线一定用尺，线才会直。

three steps to find the line = tiga langkah mencari paksi simetri Step one: fold the paper shirt from left to right, sleeve onto sleeve and collar onto collar, until the edges match exactly. Step two: open it and see the crease left down the middle. Step three: lay a ruler on the crease and draw a straight pencil line; that is the shirt's line of symmetry, its only one. Example: if the sleeves do not line up after folding, fold it again. Watch out: always draw the line with a ruler so that it is straight.

打开以后 = selepas membuka lipatan 打开纸衣服后，要把尺对准中间的折痕，再用铅笔沿着尺画线。不用尺，线容易画弯，就不准了。再斜着折一次，衣服两边不会重合，找到的也不是对称轴。 例子：画对称轴就像画格子线，尺要压稳再画。 注意：线要从衣服顶端画到底端，整条画完。

after opening the fold = selepas membuka lipatan Once the shirt is opened, line the ruler up with the crease in the middle and draw along it in pencil. Without a ruler the line easily bends and is no longer accurate. Folding again on a slant would not make the halves match, so that is not a line of symmetry. Example: drawing a line of symmetry is like ruling a line in your exercise book; hold the ruler firmly first. Watch out: draw the line all the way from the top of the shirt to the bottom.

横着折 = lipat mengufuk 衣服上半部有领口和两只袖子，下半部只是一块长方形的衣身。横着折，上面和下面形状完全不同，不会重合。所以横线不是对称轴，纸衣服只有竖着的那 1 条对称轴。 例子：裤子也是左右对称，上下不对称。 注意：试过横、竖、斜三种折法，才能确定一共有几条。

folding flat = lipat mengufuk The top half of the shirt has the collar and two sleeves, while the bottom half is just a plain rectangle of body. Folding top to bottom, the shapes are completely different and cannot match. So the flat line is not a line of symmetry, and the shirt has only its 1 upright line. Example: a pair of trousers is also symmetrical left to right but not top to bottom. Watch out: try upright, flat and slanting folds before deciding how many lines there are.

四个图形 = empat bentuk；平行四边形 = segi empat selari 再剪四个图形：正方形、长方形、正六边形和平行四边形。每个都试着竖折、横折、斜折，能完全重合的折法有几种，就有几条对称轴。把找到的折痕都用尺画出来，最后数一数。 例子：正方形试到第三种、第四种斜折时，也会重合。 注意：每找到一条就画出来，免得重复数。

four shapes = empat bentuk; parallelogram = segi empat selari Now cut out four more shapes: a square, a rectangle, a regular hexagon and a parallelogram. Fold each one upright, flat and slanting; the number of folds that match exactly is the number of lines of symmetry. Rule along each crease you find, then count them. Example: on a square, the third and fourth folds along the diagonals also match. Watch out: draw each line as soon as you find it so you do not count it twice.

配对结果 = padankan hasil 正方形 4 条（横、竖、两条斜）。长方形 2 条（只有横和竖，斜折会露角）。正六边形 6 条：3 条连对面顶点，3 条连对面边的中点。平行四边形 0 条，怎么折都对不齐。 例子：正五边形就有 5 条对称轴。 注意：平行四边形看起来整齐，但一条对称轴也没有。

matching the results = padankan hasil Square: 4 lines (upright, flat and two diagonals). Rectangle: 2 lines (upright and flat only, since diagonal folds stick out). Regular hexagon: 6 lines, 3 joining opposite corners and 3 joining the middles of opposite sides. Parallelogram: 0, because no fold makes it match. Example: a regular pentagon has 5 lines of symmetry. Watch out: a parallelogram looks tidy, yet it has no line of symmetry at all.
