Yes, they can.Yes, they can. In a symmetric distribution they will be the same.
Symmets is related to the definition of a symmetric shape.
Triangle means 3 angles. No other shape exists and any three angle shape is a triangle
a circle is symmetric so is a triangle, a rectangle.
Yes it has 3
Yes a triangle is a 2D polygon shape
if you fold a shape and it is not crocked or too big or small that and it is equal that is how you know it is a symmetric
Yes because a triangle is a 2D shape whereas a triangle prism is a 3D shape
Yes, a shape is symmetrical if it can be cut in half in any way, and be the same on both sides.
It can be but it doesn't have to be. Some are and others aren't.
