How is a square altered to result in a rhombus?
How is a square altered to result in a rhombus?
Both squares and rhombi are quadrilaterals and parallelograms. Quadrilaterals are four sided figures and parallelograms are figures that have opposite sides that are parallel.
Squares by definition contain four 
angles; rhombi on the other hand have two sets of opposite congruent angles. Therefore, for a square to to altered into a rhombus, the interior angles must be altered.

Given the following ray, construct an angle that is
In order to construct a 
angle using a ray, first recall what a 
angle and ray are.
An angle in the most basic terms is when two rays having the same vertex, are going in different directions.
Now, recall that a 
angle occurs when the lines or rays of the angle intersect perpendicularly.
Since the problem gives the starting ray,
which is a horizontal ray, then to create a 
angle, a vertical ray needs to be constructed from the same vertex. To identify a 
angle it is common practice to draw a square at the vertex to show the angle measurement. This results in the final solution.

Given a line, what is the first step taken to construct a parallel line?
To identify the first step that must be taken when constructing a parallel line, there is some information about the given line that needs to be clearly established first.
First recall what it means to be parallel. For lines to be parallel, their slopes must be equal and they must have different 
and 
intercepts. If two lines have the same intercepts and the same slope they are not parallel lines, they are the same line. Parallel lines mean that two lines will never intersect.
From here, look at the possible answers to decide which one is best.
"Identify the two lines intersection point." by definition of parallel lines this is false since parallel lines never intersect.
"Find the 
-intercept of the given line." and "Find the 
-intercept of the given line." could possible be considered among the steps to constructing parallel lines but not necessarily.
"Take the negative reciprocal of the given line's slope." Taking this would give the slope of a perpendicular line.
"Calculate the slope of the given line." in order to construct a parallel line, the slope must first be calculated on the given line. Therefore, this is the best answer.

"Calculate the slope of the given line." in order to construct a perpendicular line, the slope must be calculated on the given line.
"Either calculate the slope of the given line or identify the intersection point of the two lines."

Determine whether the statement is true or false:
Lines that have fractional slopes cannot be perpendicular to other lines.
For two lines to be perpendicular they must intersect at one point and have the opposite reciprocals on each other. Having slopes that are opposite reciprocals creates a 
angle between the two lines which is also by definition makes the two lines perpendicular.
Therefore, a line that has a fractional slope can also have a perpendicular line. If the line in question has a slope of
