Will give brainly .Which statements are true regarding undefinable terms in geometry? Check all that apply.
babymother [125]

The true statements about terms in geometry that are undefinable are;

  • A point has no length or width
  • A point indicates a location on the coordinate plane
  • A line consists of an infinite set of points.
  • A plane consists of an infinite set of points.

<h3>How can the true statements be found?</h3>

Three undefinable terms in geometry are;

1) Point

2) Line

3) Plane

The above terms do not have a formal definition but they can be described based on their properties.

The other geometric terms are defined based on the above undefinable terms.

A point can be described as a location in space that is dimensionless and can be specified on the coordinate plane as an ordered pairs (x, y).

True statements about a point are therefore;

  • A point has no length or width
  • A point indicates a location on the coordinate plane

A line is infinitely long, that has no beginning or end. It has one dimension, with no thickness or height.

Given that a point is dimensionless, a line can be considered a set of points.

A true statement is therefore;

  • A line consists of an infinite set of points.

A plane is a two dimensional geometric figure that have infinite length and width.

An infinite set of lines that forms a two dimensional figure can be used to describe a plane.

The true statement with regards to a plane is therefore;

  • A plane consists of an infinite set of points.

What are the values of a and b? O a 14, b=6 O a=14, b = 8 O a=17, b = 6 O a = 17, b = 8​
ycow [4]

The value of a is 17 and the value of b is 6. The correct option is third option a = 17, b = 6

<h3>Calculating the length of the sides of a kite </h3>

From the question, we are to determine the values of a and b

From the given kite diagram, we can conclude that

/FG/ = /HG/

Thus,

30 =  2a - 4

∴ 2a - 4 =  30
2a = 30 + 4

2a = 34

a = 34 / 2

a = 17

Also,

/FJ/ = /HJ/

3b + 6 = 24

3b = 24 - 6

3b = 18

b = 18/3

b = 6

Hence, the value of a is 17 and the value of b is 6. The correct option is third option a = 17, b = 6
