Teroka Ria

Mulakan pada titik pertama dan sambungkan titik satu demi satu hingga kembali ke titik mula.

Teroka Ria
Langkah 1

Sambung titik mengikut urutan

Mulakan pada titik pertama dan sambungkan titik satu demi satu hingga kembali ke titik mula.

A → B → C → A
sambung titik = 连点
从第一个点开始,按顺序一个接一个连,最后要连回起点,图形才会封闭。例如 A 到 B、B 到 C,再回到 A。
例子:4 个点 P、Q、R、S,连 P-Q、Q-R、R-S、S-P,共 1 + 1 + 1 + 1 = 4 条边。
注意:最后一步最容易忘,没连回起点就会少一条边。
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 A, B dan C yang betul ialah…

urutan sambung titik = 连点的顺序
题目问:连 A、B、C 三个点,正确的顺序是哪一个。检查方法:每个点都要用到,按字母顺序连,而且最后图形要封闭,没有缺口。
例子:5 个点连成封闭图形,需要 1 + 1 + 1 + 1 + 1 = 5 条线。
注意:数一数每个选项会画出几条线,再想能不能围起来。
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.
