What are the 3 types of geometry?

In two dimensions there are 3 geometries: Euclidean, spherical, and hyperbolic. These are the only geometries possible for 2-dimensional objects, although a proof of this is beyond the scope of this book.

What is a proper notation?

Why are there no parallel lines on a sphere?

In spherical geometry Parallel lines DO NOT EXIST. In Euclidean geometry a postulate exists stating that through a point, there exists only 1 parallel to a given line. … Therefore, Parallel lines do not exist since any great circle (line) through a point must intersect our original great circle.

What is notation mean?

1 : annotation, note. 2a : the act, process, method, or an instance of representing by a system or set of marks, signs, figures, or characters. b : a system of characters, symbols, or abbreviated expressions used in an art or science or in mathematics or logic to express technical facts or quantities.

How do you write an AB line?

A line is one-dimensional and has no width. It is identified by naming two points on the line or by writing a lowercase letter of choice after the line. The notation, for example, AB (written with a line symbol <---> over the letters), is read as “line AB” and refers to the line that has points A and B.

Is Line AB the same as BA?

This line-segment is called AB. It may also be called BA. Line BA is the same as line AB. Both pass through the same two points A and B.

What does an upside down T stand for?

Perpendicular Line: Perpendicular lines are lines that meet or cross to form a right angle. … A perpendicular symbol is simply an upside down capital letter T. It looks like this: Adjacent angles: Two angles are adjacent if they have the SAME VERTEX, share ONE SIDE and do not overlap.

What does this symbol mean ⊥?

The up tack or falsum (⊥, \bot in LaTeX, U+22A5 in Unicode) is a constant symbol used to represent: The truth value ‘false’, or a logical constant denoting a proposition in logic that is always false (often called “falsum” or “absurdum”).

How do you prove parallel lines?

If two parallel lines are cut by a transversal, then corresponding angles are congruent. If two lines are cut by a transversal and corresponding angles are congruent, then the lines are parallel.

What is proper mathematical notation?

Definition. A mathematical notation is a writing system used for recording concepts in mathematics. The notation uses symbols or symbolic expressions that are intended to have a precise semantic meaning. In the history of mathematics, these symbols have denoted numbers, shapes, patterns and change.
