Geometry

reflex angle

Mathematics; Geometry

An angle with measure greater than 180o but less than 360o.

sides

Mathematics; Geometry

The line segments that form a polygon.

semicircles

Mathematics; Geometry

The two arcs of a circle that are cut off by a diameter. The measure of a semicircle is 180.

pie graph

Mathematics; Geometry

A circle marked into sectors. Each sector shows the fraction represented by one category of data. Pie graphs are also called circle graphs.

octahedron

Mathematics; Geometry

A polyhedron with eight faces. All faces of a regular octahedron are congruent, equilateral triangles.

opposite angles

Mathematics; Geometry

In a quadrilateral, angles that do not have a common side--that is, non-adjacent angles.

line of symmetry

Mathematics; Geometry

A line dividing a two-dimensional figure into two parts that are mirror images of each other.
