sambung titik = join the dots Start at the first dot and join the dots one after another in order, then return to the start so the shape is closed, for example A to B, B to C, and back to A. Example: dots P, Q, R and S joined as P-Q, Q-R, R-S and S-P give 1 + 1 + 1 + 1 = 4 sides. Watch out: the last line back to the start is easy to forget, leaving one side missing.
Langkah 2
Periksa ciri bentuk
Kira sisi lurus, sisi melengkung dan bucu untuk mengenal pasti bentuk yang terhasil.
kira sisi + kira bucu → nama
kira sisi dan bucu = 数边和顶点 连好后,数一数有几条直边、几条曲边、几个顶点,再说出图形的名字。3 条直边和 3 个顶点是三角形,4 条直边是四边形。 例子:图形有 4 条直边,对边是 7 cm 和 3 cm,一圈 7 + 3 + 7 + 3 = 20 cm,是长方形。 注意:曲边也是边,但有曲边的图形不是三角形或四边形。
kira sisi dan bucu = count sides and vertices After joining, count the straight sides, curved sides and vertices, then name the shape. Three straight sides make a triangle. Example: a shape with opposite sides of 7 cm and 3 cm measures 7 + 3 + 7 + 3 = 20 cm around and is a rectangle. Watch out: a curved side still counts as a side, but it stops the shape from being a triangle.
Langkah 3
Banding hasil
Dua lukisan boleh mempunyai nama bentuk yang sama walaupun saiz atau arah berbeza.
saiz berbeza · arah berbeza · bentuk sama
saiz berbeza · arah berbeza = 大小不同、方向不同 两个人画出的图形,大小或方向可能不同,但只要边和顶点的数目、特征一样,名字就一样。 例子:一个三角形边长 3 cm,另一个 6 cm,大的边长是小的 6 ÷ 3 = 2 倍,两个都还是三角形。 注意:正方形转一个角度看起来像菱形,但它还是正方形。
saiz berbeza · arah berbeza = different size, different direction Two drawings may differ in size or direction, yet if they have the same number and kind of sides and vertices, they share a name. Example: one triangle has 3 cm sides and another 6 cm sides; the bigger is 6 ÷ 3 = 2 times as long. Watch out: a square turned on its corner looks like a diamond, but it is still a square.

urutan sambung titik = order of joining dots The question asks for the correct way to join dots A, B and C. Check that every dot is used, that the letters follow their order, and that the final shape is closed with no gap. Example: closing a shape with 5 dots needs 1 + 1 + 1 + 1 + 1 = 5 lines. Watch out: count how many lines each choice would draw, then ask whether they can enclose a space.

Tiga titik yang tidak sebaris boleh membentuk…
tiga titik tidak sebaris = 不在一直线上的三个点 题目问:三个不在同一直线上的点连起来,会得到什么图形。可以在纸上点三个点,自己连连看来检查。 例子:如果三个点排成一直线,连起来只是一条线段,长度 3 + 4 = 7 cm。 注意:漏读 tidak,意思就完全相反。
tiga titik tidak sebaris = three dots not in a line The question asks what shape forms when three dots that are not in a straight line are joined. Check by drawing three dots on paper and joining them. Example: if three dots did lie in a row, joining them gives just one line of 3 + 4 = 7 cm. Watch out: tidak sebaris means not in a line; missing the word tidak flips the meaning.
