What is another word for plane geometry?
Pronunciation: [plˈe͡ɪn d͡ʒiˈɒmətɹˌi] (IPA) 
Plane geometry is a branch of mathematics that deals with two-dimensional figures such as points, lines, triangles, and circles. Synonyms for the word "plane geometry" include Euclidean geometry, flat geometry, and two-dimensional geometry. Euclidean geometry is named after the Greek mathematician Euclid and is the most common type of geometry studied in schools. Flat geometry emphasizes on the properties of two-dimensional shapes and is concerned with the principles of measurement of surfaces and lines. Two-dimensional geometry covers the study of angles, shapes and sizes of plane figures, including polygons, circles, and triangles. Regardless of what it is called, the study of plane geometry is essential in the practical applications of mathematics in various fields.
