A side of an equalateral triangle is 2/8 cm long. Draw a picture that shows the triangle. What is the perimeter of the triangle?
2/8 of a centimeter? Are you sure?
To draw a picture of an equilateral triangle with a side length of 2/8 cm, follow these steps:
1. Take a ruler and draw a horizontal line segment. This will be the base of your equilateral triangle.
2. From one endpoint of the base, use the ruler to draw a line segment at a 60-degree angle. This will be one side of the triangle.
3. Repeat step 2 from the other endpoint of the base to draw the other side of the triangle.
4. Finally, connect the endpoints of the two side segments to complete the equilateral triangle.
Now, to find the perimeter of the triangle:
Since an equilateral triangle has three equal sides, and each side of this triangle is 2/8 cm long, we can find the perimeter by multiplying the side length by 3.
Perimeter = (2/8 cm) * 3 = (2 cm) / (8 cm) * 3 = 6/8 cm = 3/4 cm.
Therefore, the perimeter of the equilateral triangle is 3/4 cm.
