Why are undefined terms in geometry called undefined?

The undefined terms in geometry called undefined because using the three undefined terms (point, line and plane) we can define other terms in geometry.

Step-by-step explanation:

In geometry, we have three undefined terms: point, line and plane.

An expression in mathematics is said to be undefined if it does not have any meaning but it is used to define other mathematical terms.

Similarly the undefined terms in geometry are words that don't require any formal definition. They create the building blocks for either properly defining or proving  theorems and other terms.

Generally we can say that by using the three undefined terms (point, line and plane) we can define other terms in geometry.

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )
