Have a look here: Rotational Symmetry
Hey,
i'm new to this forum so sorry if i do anything wrong,
and you guys are probably like maths geniuses so i probably seem very dumb but i'm stuck on my homework.
The question is:
---------------------------------------------------------
The diagram shows part of a shape.
The shape has rotational symmetry of order 2 about x.
a. Copy and complete the shape, and name it.
b. Show how the completed shape will tessellate.
---------------------------------------------------------
I've tried to draw the diagram as best as i could on paint, It's in an attachment.
I understand the questions, but not,
'The shape has rotational symmetry of order 2 about x'
Do they mean spin the triangle around on the point of x and it has 2 rotational symmetries?
If so, how can i complete the shape?
