A shape has a line of symmetry when the folded part sits perfectly on top with all edges matching. The number of lines of symmetry in a regular polygon is equal to the number of sides. A shape has ...

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

More simply, the angle at the centre is double the angle at the circumference. Angle OGK (\(x\)) = angle OKG because triangle GOK is also isosceles. Lengths OK and OG are also both radii. Angle GOH = ...

The angle at the circumference in a semicircle is 90°. Angle STU = 90° Angles in a triangle add up to 180°. The angle on a straight line is 180°. The angle VOY = 180°. The angle at the centre is ...
