Describe what collinear points are.
Points that are on the same line.
100
Describe a midpoint.
A point that splits a line segment exactly in half; or a point that bisects a line segment.
100
What is the midpoint formula?
(x1 + x2 divided by 2, y1 + y2 divided by 2)
100
Describe what adjacent angles are.
Angles that are right next to each other and share a side/ray.
100
How do you find the circumference of a circle?
multiply the diameter by pi or multiply 2*pi*the radius
200
What does it mean to be congruent?
To be the same length or size.
200
What is the criteria for an angle to be obtuse?
It must be greater than 90 degrees and less than 180 degrees.
200
What is the distance formula?
Distance = square root[(x1 - x2)^2 + (y1 - y2)^2]
200
Describe the difference between supplementary and complimentary angles.
supplementary angles add to 180 degrees. complimentary angles add to 90 degrees.
200
Find the Area and Perimeter of the figure on slide 4
A=44 P=30
300
What are two ways to show congruency?
The congruency symbol (must be shown) and tick marks.
300
What criteria must be true for a point to be "between" two other points?
All three points must be collinear (on the same line).
300
Find the midpoint between the two points (2,2) and (4,-3).
(3,-1/2)
300
Describe why angles that are a linear pair are or are not also supplementary.
A linear pair of angles are also supplementary because a linear pair make a straight line, which is 180 degrees as are supplementary angles.
300

Describe the difference between...(see slide 1)
AB is referring to the length of the segments, whereas the other is referring to the segment itself.
