A statement that is believed to be true but has not yet been proven.
What is a conjecture?
If all squares are rectangles and all rectangles have four sides, we can deduce that all squares have this.
what is four sides
what is a line made up with
what is points that have width or thickness
A line segment that divides another line segment into two equal parts.
Two angles that add up to 180° are called this.
what is supplementary angles
An example that shows a conjecture is false.
What is a counterexample?
In mathematics, proving a theorem using definitions, postulates, and previously proven theorems is an example of this type of reasoning.
what is deductive reasoning
a plane containing point S and point T
One plane that can be named is plane A. You can also use the
letters of any three noncollinear points to name this plane. Plane
TRS and plane TQS can be used to name this plane.
what is another correct name for plane A.
plane QST, plane STV, plane QVS, plane VST
what is plane QST
The midpoint formula finds this point on a line segment.
what is midpoint
Angles that share a common vertex and a common side, but do not overlap, are called this.
What are adjacent angles?
The conjecture “All numbers divisible by 4 are divisible by 8” is false; the number 12 serves as this. is this a counterexample or conjecture
What is a counterexample?
Determine whether the conclusion of one statement is the

A segment that connects a vertex of a polygon to the midpoint of the opposite side.
what is median
The distance formula in a coordinate plane comes from this famous theorem.
What is the Pythagorean Theorem?

A line lies entirely within this when all its points satisfy the plane’s equation.
what is the plane
The segment connecting the midpoints of two sides of a triangle.
what is midsegment
Two angles on opposite sides of intersecting lines are equal; they are called this.
What are vertical (opposite) angles?
A conjecture can be based on a pattern, but mathematicians always seek this to confirm its truth for all cases.
