4.4 - 4.6 Flashcard Review

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What is the property of vertical angles?

Back

Vertical angles are congruent, meaning they have the same measure.

Front

What are alternate interior angles?

Back

Angles that lie between two parallel lines on opposite sides of a transversal. They are congruent.

Front

What does it mean for triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, which can be shown using congruence statements.

Front

What is a congruence statement?

Back

A statement that shows two geometric figures are congruent, such as ΔABC ≅ ΔDEF.

Front

How do you find the value of x in an equation?

Back

Isolate x by performing inverse operations on both sides of the equation.

Front

If ΔDEF ≅ ΔRST, what can we conclude about the sides?

Back

The corresponding sides are equal: DE = RS, EF = ST, DF = RT.

Front

What is the definition of bisect?

Back

To divide an angle or a segment into two equal parts.

Front

What are consecutive angles?

Back

Angles that are on the same side of a transversal and between the two lines.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.
