Since the curriculum reform, some teachers have always had doubts about whether to use "connection" or "connection" in junior high school mathematics. Now I want to talk about this problem.

"Connecting AB" (connecting with line segments) used to be written as "Connecting AB". The First List of Variant Characters compiled by the State Language Committee on March 3, 20021day recommended the use of "connecting" or "connecting", but did not advocate the use of "connecting" or "connecting", so this set of textbooks uses "connecting" uniformly.

As for the other meaning of "connection", it means that the straight line (or the circle where the arc is located) and the circle where the arc is located are tangent to a certain point and are on both sides of the radius of the tangent point (or the connecting line). This is actually a smooth connection between "lines and arcs" or "arcs and arcs". This content originally belonged to junior high school mathematics, but it was deleted from the mathematics curriculum standard published by the Ministry of Education in 200 1.

In short, there were two kinds of "connections" in junior high school mathematics in the past, so the textbook writing department used to write the line segment connection as "connection" to show the difference. At present, there is only one kind of "connection" in junior middle school mathematics, and the relevant state departments also have relevant regulations on language and writing, so the textbook only uses "connection" instead of "connection" according to this regulation.
