Q

Deductive Reasoning

A

Means we can draw a conclusion based on at least two true statements, or premises. Because the statements are true, we know that the conclusion we make based on those two statements is also true.

Conjecture

A

conjectureis a statement believed to be true based on observations.

Looking at the following numbers: 2, 4, 6, 8, 10, 12. What would be the next number? Most likely, you are thinking 14.

Q

Coefficent

A

Coefficientsare the multiplicative numbers located directly in front of a variable, such asxory. If a number in an equation is not connected with a variable, that number is not considered a coefficient. Instead, it is called aconstant.

Coefficients can be positive or negative and real or imaginary, as well as decimals, fractions, or whole numbers.

Q

Transversal

A

Atransversalis two parallel lines intersected by a third line at an angle. The third line is referred to as the transversal line. When this line happens, several angles are created.

You can use these angles to find the measurements of other angles.

Q

Congruent

A

For shapes to be congruent they must be the same shape and size. You may have to turn one of the shapes, but if they match exactly, then they are congruent

Q

Alternate Exterior Angles

A

When you have two lines and a third line crossing through them, the pairs of angles that are outside both lines and on alternating sides of the third line are youralternate exterior angles.

Q

Proof

A

Amathematical proofshows a statement to be true using definitions, theorems, and postulates. Just as with a court case, no assumptions can be made in a mathematical proof. Every step in the logical sequence must be proven.

Mathematical proofs usedeductive reasoning, where a conclusion is drawn from multiple premises. The premises in the proof are called statements.
