Three lines of symmetry on an equilateral triangle. Right-angled triangles follow the same rules as other triangles. It's not the right angle that matters but whether the triangle is scalene or ...

Each angle is the same size. Each angle is 60°. Image caption, An equilateral triangle has three lines of symmetry. There are three ways the triangle can be cut into a pair of mirrored halves.

You may hear students say words like ‘paralyzed’ triangle for isosceles and equilateral triangles after noticing the restrictive movements of these triangles upon dragging. Properties of symmetry: - ...

Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights ...

They often identify them solely based on their resemblance to prototypes: e.g., a shape will be called a triangle if it looks like an equilateral triangle with a horizontal base – all others are ...

Is there a term for the shape shown above: a smooth, continuous curve with three axes of symmetry ... centred on the opposite vertex of an equilateral triangle. The vertices of the triangle ...
