No, a triangle has 3 sides, a rectangle has 4
A rectangle has 4 sides, while a triangle has 3 sides.
Add together the lengths of each of its sides.
It has 3 sides.
To find the perimeter of a polygon, just add the length of all the sides. In this case, the four sides of the rectangle.
A rectangle has 4 sides whereas a triangle has 3 sides
as rectangle is to square I would say Rectangle is to Triangle. Because Hexagon-6sides, pentagon-5 sides, Rectangle-4 sides, triangle 3 sides. But that is just me :)
