Accepted Answer

# Explanation:
## Step1: Recall perpendicular - bisector property
A perpendicular bisector of a line segment divides the line segment into two equal parts. If $DG$ is the perpendicular bisector of side $EF$ and $EF = 14$ units, then $EG=GF=\frac{EF}{2}$.
## Step2: Calculate lengths of $EG$ and $GF$
$EG = GF=\frac{14}{2}=7$ units.

# Answer:
d. $EG = 7$ units, $GF = 7$ units

# Explanation:
## Step1: Analyze vertices of a regular hexagon
A regular hexagon has 6 vertices. To form an equilateral triangle by connecting vertices of a regular hexagon inscribed in a circle, we consider the geometric relationships.
## Step2: Count the number of equilateral triangles
We can form 2 non - overlapping equilateral triangles by connecting the vertices of a regular hexagon inscribed in a circle. For example, if the vertices of the hexagon are $A,B,C,D,E,F$ in order, $	riangle ACE$ and $	riangle BDF$ are equilateral triangles.

# Answer:
c. 2

# Explanation:
## Step1: Understand honeycomb structures
Honeycomb structures are known for their efficient use of materials and strength - to - weight ratio.
## Step2: Identify the reason for using hexagons
Hexagons are used in honeycomb structures to maximize strength while minimizing weight. The hexagonal shape distributes stress evenly and fills space efficiently without leaving gaps.

# Answer:
a. To maximize strength while minimizing weight

# Explanation:
## Step1: Recall proof types
There are different types of geometric proofs such as paragraph proof, indirect proof, flowchart proof, and two - column proof.
## Step2: Identify the proof with statements and reasons side - by - side
In a two - column proof, we have two columns. One column lists the statements and the other column lists the corresponding reasons for those statements.

# Answer:
d. Two - column proof

# Explanation:
## Step1: Recall the condition for parallel line segments
Two line segments in a coordinate plane are parallel if and only if their slopes are equal.
## Step2: Analyze the options
Checking if they intersect is for non - parallel lines (intersecting or skew in 3D), measuring angles is for checking if lines are perpendicular or for angle - related properties in a geometric figure, and measuring lengths has nothing to do with parallelism.

# Answer:
b. By showing their slopes are equal

# Explanation:
It is not clear what the "To Prove" section in a geometric proof refers to in the provided options as they seem to be incomplete or not well - formed. However, in a geometric proof, the "To Prove" section states the proposition or conclusion that we are trying to demonstrate. But since the options are not clear in terms of correct terminology, we assume there is an error in the question setup.

# Answer:
No correct option among the given ones

# Explanation:
It is not clear what the equation $2r-3r = 4$ has to do with the context of the previous questions. If we solve the equation $2r-3r = 4$, we combine like terms:
## Step1: Combine like terms
$2r-3r=(2 - 3)r=-r$. So the equation becomes $-r = 4$.
## Step2: Solve for $r$
Multiply both sides by $- 1$ to get $r=-4$. But since the question seems to be out of context with the previous ones and no options are provided for this equation - solving part, we assume it is a mis - placed or incomplete part of the question set.

# Answer:
No correct option among the given ones (as no options for this equation part)
