Front

What does the Alternate Exterior Angles Theorem state?

Back

If a pair of parallel lines is cut by a transversal, then alternate exterior angles are congruent.

Front

What does it mean if ∠A ≅ ∠B?

Back

m∠A = m∠B because of the Definition of Congruent.

Front

If 3x = 15, what is the value of x?

Back

x = 5 using the Division Property of Equality.

Front

What assumption is made to start the indirect proof of ∆ABC≅∆DEF?

Back

Assume ∆ABC≇∆DEF.

Front

What transformation occurs from triangle ABC to triangle A'B'C'?

Back

Reflection across the x-axis.

Front

What is the definition of congruent angles?

Back

Angles that have the same measure.

Front

What is the Division Property of Equality?

Back

If you divide both sides of an equation by the same non-zero number, the two sides remain equal.

Front

What is the purpose of an indirect proof?

Back

To assume the opposite of what you want to prove and show that this assumption leads to a contradiction.

Front

What is a transversal in geometry?

Back

A line that intersects two or more lines at different points.

Front

What are alternate exterior angles?

Back

Angles that lie outside the two lines and on opposite sides of the transversal.
