Name the transversal.
|
Line segment EF is the transversal |
|

Line segments AB and CD are paralle |
|
Name the vertical angle congruent to angle CKF |
Angle DKE is vertical and congruent To angle CKF |
|
|
Define a transversal.
|
Transversals are lines or line segments that intersect 2 or more lines. |
|
|
Define parallel lines.
|
Parallel lines are equidistant from each other and never intersect. |
|
|
Define vertical angles.
|
Vertical angles are formed by intersecting lines and share a common vertex but do not share a common side. They are congruent angles. |
|
|
Define adjacent angles.
|
Adjacent angles share a common vertex and share a side. Adjacent angles formed by intersecting lines are supplementary. |
|
|
Define supplementary angles.
|
The sum of supplementary angles is 180 degrees. Adding supplementary angles will result in a 180 degree angle, forming a straight line. |
|
If angle EHB measures 60 degrees, what is the measure of angle AHF? |
Angle AHF measures 60 degrees. Vertical angle rule. |
|
|
Define alternate angles.
|
Alternate angles are on different sides of a transversal but not adjacent. There are alternate interior and alternate exterior angles. Alternate angles are congruent. |
|
|
Define same side angles.
|
Same side angles are on the same side of a transversal. Same side interior and same side exterior angles are supplementary. Same side corresponding angles are congruent. |
|
|
Define Interior angles.
|
Interior angles are formed by a transversal and found in between parallel lines. |
|
|
Define Exterior angles.
|
Exterior angles are formed by a transversal and found outside of the parallel lines. (or on the outside of polygons, for future reference.) |
|
Angle AHE is _____________ to opposite exterior angle DKF |
Congruent |
|
Name an exterior angle that is supplementary |
Angles AHE, BHF CKE and DKF are all supplementary to angle BHE. |
|
If angle DKF measures 110 degrees. What is the measure |
BHF also measures 110 degrees, because corresponding angles are congruent. |
|
If angle AHF measures 75 degrees, what is the measure of angle AHE and why? |
Angle AHE measures 105 degrees because it is supplementary to AHF. 75 + 105 = 180 |
|
If angle DKF measures 115 degrees, what is the measure |
Angle CKE measures 115 degrees because it is a vertical angle to angle DKF and vertical angles are congruent. |
|
|
A linear function will have a ___________ rate of change.
|
Constant |
|
|
What are the rules for slope intercept form of a linear equation?
|
The y variable must have a coefficient of one and be the only term on one side of the equal sign. (Either left or right side, as long as the y is alone.) |
|
|
What are the rules for standard form of a linear equation?
|
The x and y terms must be on the same side of the equal sign: The x term must come first and have an positive integer coefficient: |
|
|
Define Coefficient.
|
A number multiplied by a variable in an equation. |
|
|
Define Constant |
A constant in an equation is a term not being multiplied by a variable. For example, 25 is a constant in the following equation. y=2x+25. In slope intercept form, the constant is also the y intercept. |

|
y = -10 |

|
Graph. |
|
|
|
How is the equation for a flat line unique.
|
It is missing the variable x because the slope is zero. The y value is constant and not dependent on x making the equation look like y = 5. |

|
|
How do you find the median?
|
First put the numbers in order from least to greatest. Then find the number in the middle. |
