A _____________ is a measurable part of a line that
consists of two points, called endpoints, and all of the
points between them. The two endpoints are used to
name the segment.

Conjectures and Counterexamples/Statements Conditionals and Biconditionals

100

A statement that appears to be true but hasn't been proven.

Conjecture

200

An example that shows a conjecture is false.

Counterexample

300

If you risk nothing, then you risk everything.

Hypothesis: You risk nothing. Conclusion: You risk everything.

400

Write the converse, inverse, and contrapositive of the statement (If there is no struggle, there is no progress)

• Converse (If Q, then P): If there is progress, then there is a struggle.
• Inverse (If not P, then not Q): If there is a struggle, then there is progress.
• Contrapositive (If not Q, then not P): If there is progress, then there is a struggle

supplementary angles is 180°

Hypothesis: Two angles are supplementary.
Conclusion: The sum of their measures is 180°

what is the solution?

Angle A and Angle B are supplementary.
If Angle A = 50°, find Angle B.

Angle B = 180° − 50° = 130°
