Question

write the sequences of the perimeters of the equilateral triangle having 1cm,2cm,3cm

1) write the sequences of area
2) write the sequences of
angle sums​

Answer 1

Answer:

Given:

Sides of the triangles are 1cm, 2cm, 3cm, 4cm etc.

To find:

The sequence of the perimeter of the triangle.

Solution:

1) Equilateral triangle whose all sides are equal to each other and all the angles are equal is of 60° each.

2) Perimeter of any triangle is equal to the sum of all the sides of the triangle and for equilateral triangle it is 3×side.

3) So the sequence of the perimeter of the triangle is:

3×1, 3×2, 3×3, 3×4.. etc

3, 6, 9, 12, ... etc.

The sequence of the perimeter of the triangle is 3, 6, 9, 12 .. etc.
