Which statements are true regarding undefinable terms in geometry? Select two options. D.Apoint's kection on the coordinate plane is indicated by an ordered pair, (x,y) A point has one dimenoion length. A line has length and with A distance along a line must have no beginning or end A plane consists of an infinite set of points.

## Step 1: Understanding Undefinable Terms<br />### Undefinable terms in geometry are basic concepts that are intuitively understood but lack a formal definition. They form the foundation upon which other geometric concepts are built. These typically include points, lines, and planes.<br /><br />## Step 2: Analyzing Option D<br />### Option D states that a point's location on the coordinate plane is indicated by an ordered pair $(x,y)$. This is a correct statement about how we represent points, but it doesn't define what a point *is*. Points exist regardless of coordinate systems.<br /><br />## Step 3: Analyzing Option A<br />### Option A states that a point has one dimension: length. This is incorrect. A point has no dimension; it represents a location in space.<br /><br />## Step 4: Analyzing Option B<br />### Option B states that a line has length and width. This is incorrect. A line has only one dimension: length. It extends infinitely in both directions but has no width.<br /><br />## Step 5: Analyzing Option C<br />### Option C states that a distance along a line must have no beginning or end. This is incorrect. A distance is a measurable segment of a line and therefore *must* have a beginning and an end.<br /><br />## Step 6: Analyzing Option E<br />### Option E states that a plane consists of an infinite set of points. This is a true statement. A plane is a two-dimensional flat surface that extends infinitely and is made up of an infinite number of points.
