Circle
A shape made of all points that are the same distance from a center point.
Which construction can be used to determine whether point C is closer to A point or point B ?
Construct the perpendicular bisector of segment AB
A triangle has side lengths of 5 cm, 7 cm, and 9 cm. What type of triangle is it?
Scalene
Finish the quote: “The inner machinations of my mind are an _____.”
Enigma
Lines in the same plane that never intersect, no matter how far they are extended.
Parallel
When constructing a perpendicular bisector of segment AB, you draw circles centered at A and B. Why must the circles overlap?
To create two intersection points that can be connected to form the perpendicular bisector.
A triangle has side lengths of 8 inches, 5 inches, and 8 inches. What type of triangle is it?
Isosceles
I have 1 equalateral triangle, 1 isocleles triangle, and 1 scalene triangle. How much do all the angles add up to?
540 Degrees
A ray or line that divides an angle into two equal parts.
Angle Bisector
Jimmy draws a circle centered at point A. Without changing the compass width, he draws another circle centered at point B. The two circles intersect above and below segment AB. If Jimmy draws a line through those two intersections, what has he constructed?
Perpendicular bisector of segment AB.
Sally draws a straight path that starts at point A, passes through point B, and continues forever in the same direction. Is this a line, line segment, or ray?
Ray
In Shrek, what does Shrek compare ogres to?
A part of a line that starts at one point (endpoint) and goes on forever in one direction.
Ray
Kim constructs a perpendicular line to line m through point P. She then constructs another line perpendicular to her new line through a different point. What is the relationship between the final line and line m?
Parallel
A triangle has two sides that are the same length. What must be true about the angles opposite those two sides?
The two angles have the same measure.
You have 10 fish in a tank. Two fish drown, three swim away, and one dies. How many fish are still in the tank?
10 - no fish were taken out of the tank and they can't swim away.
The point where two or more lines, rays, or segments meet.
Vertex
Benny is constructing a perpendicular line through point P on line m. After drawing a circle centered at P, the circle crosses line m at points A and B. He then draws equal-sized circles centered at A and B that intersect at point C. What should Benny do next to finish the construction?
Draw a line through points P and C
Point A is located on a line. Point B is 6 units away from A in one direction, and point C is 6 units away from A in the opposite direction. What is point A in relation to segment BC?
Point A Is the midpoint of segment BC
What comes next in this pattern: 2, 6, 12, 20, 30, ___?
42 (+4, +6, +8, +10, +12)
