A triangle is three currents that do not lie on one straight line, connected by segments. In this case, the points are called the vertices of the triangle, and the segments are called its sides.
Equilateral is a triangle in which all three sides are equal:
AB = BC = AC = 4 cm.
The perimeter of a triangle is equal to the sum of all its sides:
P = AB + BC + AC;
P = 4 + 4 + 4 = 12 cm.
Answer: The perimeter of an equilateral triangle is 12 cm.
