What do the sides of a triangle add up to?
Basically, a triangle is a closed 2D shape that has 3 angles, 3 vertices, and 3 sides.
Answer: The sides of a triangle add up to give the perimeter.
Let's find out the answer with some explanation.
We know that the sum of any 2D geometric figure is known as the perimeter.
So, if we add the sides of a triangle, we will definitely get the perimeter of the triangle.
Let's see an example of a perimeter of the triangle given below,
