W e shall match the following definitions to the appropriate headings;
(1)
[tex]\begin{gathered} \text{Slopes of parallel lines;} \\ \text{EQUAL} \end{gathered}[/tex]The slopes of parallel lines are always equal in value
(2)
[tex]\begin{gathered} \text{Slopes of perpendicular lines;} \\ \text{OPPOSITE AND RECIPROCAL} \end{gathered}[/tex]The slope of a line perpendicular to another line is a negative and at the same time a reciprocal (that is, negative inverse) of the other line.
A line with slope 3, would have a perpendicular with slope of
[tex]-\frac{1}{3}[/tex](3)
[tex]\begin{gathered} \text{ Point-slope form of a linear equation;} \\ (y-k)=m(x-h) \end{gathered}[/tex]In this case the point
[tex](h,k)[/tex]are the coordinates for the given point, while m is the slope also given.
(4)
[tex]\begin{gathered} \text{Equation of a circle;} \\ (x-h)^2+(y-k)^2=r^2 \end{gathered}[/tex](5)
[tex]\begin{gathered} \text{Slope}-\text{intercept form of a linear equation;} \\ y=mx+b \end{gathered}[/tex]Where m is the slope and b is the y-intercept.
(6)
[tex]\begin{gathered} \text{Segment in a triangle from a vertex to the midpoint } \\ of\text{ the opposite side} \end{gathered}[/tex](7)
[tex]\begin{gathered} \text{Altitude;} \\ \text{Segment in a triangle from a vertex perpendicular to the line} \\ \text{that contains the opposite side} \end{gathered}[/tex](8)
[tex]\begin{gathered} \text{Perpendicular Bisector;} \\ \text{ Line that is perpendicular to a segment at the midpoint} \end{gathered}[/tex](9)
[tex]\begin{gathered} \text{Perfect square trinomial;} \\ x^2+2xy+y^2 \\ OR \\ x^2-2xy+y^2 \end{gathered}[/tex]
