For centuries, one of algebra’s oldest puzzles has remained unsolved—how to find exact answers for higher-degree polynomials, ...

The sum of the angles inside any polygon can be found by splitting the polygon into triangles. The number of triangles that a polygon can be divided into is always two less than its number of sides.

The sum of the angles inside any polygon can be found by spitting the polygon into triangles. Consider any triangle. The sum of the angles is known to be 180° A quadrilateral can be split into ...

By doubling the number of sides of the hexagon to a 12-sided polygon, then a 24-sided polygon ... which were unknown in Archimedes' day—Archimedes used geometry instead. For example, he knew ...

Save guides, add subjects and pick up where you left off with your BBC account. Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular ...

Polygons are multi-sided shapes with different properties. Shapes have symmetrical properties and some can tessellate. Loci and constructions - Edexcel Loci are a set of points with the same ...

The number of lines of symmetry in a regular polygon is equal to the number of sides. A shape has rotational symmetry when it can be rotated and it still looks the same. The order of rotational ...
