Nyatakan jenis setiap segi tiga yang berikut. Seterusnya, lukis paksi simetri, jika ada.

Here are the types of triangles and their axes of symmetry:

• 1. The triangle has sides of lengths $3 \text{ cm}$, $3 \text{ cm}$, and $3 \text{ cm}$. Since all three sides are equal, it is an equilateral triangle. An equilateral triangle has 3 axes of symmetry. Each axis passes through a vertex and the midpoint of the opposite side.

• 2. The triangle has sides of lengths $2 \text{ cm}$, $4 \text{ cm}$, and $5 \text{ cm}$. Since all three sides are of different lengths, it is a scalene triangle. A scalene triangle has no axes of symmetry.

• 3. The triangle has sides of lengths $6 \text{ cm}$, $8 \text{ cm}$, and $6 \text{ cm}$. Since two sides are equal ($6 \text{ cm}$ and $6 \text{ cm}$), it is an isosceles triangle. An isosceles triangle has 1 axis of symmetry. This axis passes through the vertex between the two equal sides and the midpoint of the base ($8 \text{ cm}$ side).
