What shape has equal opposite sides?
An equilateral shape would have equal and opposite sides.
Median of equilateral triangle?
It is the line from a vertex of the triangle to the midpoint of the side opposite that vertex.
What are the number of lines of symmetry in an equilateral triangle?
The three lines joining each vertex to the midpoint of the opposite side. They are also the medians, altitudes and perpendicular bisectors of the sides. In an equilateral triangle these are coincident.
What is an equilateral triangle is symmetrical about?
YES!!! An equilateral triangle has three lines of symmetry. They are drawn from any one corner to the opposite base. They should all intersect at the centre of the triangle. By comparison, an Isosceles triangle has only one line of symmetry. From the one unequal angle to the opposite side. Right angled, and scalene triangles do not have lines of symmetry.
What has opposite sides parallel and 4 right angles but is not a square?
A rectangle (one that is not equilateral because then it would be a square)
