Honors Geometry 6.1 - 6.3 Flashcard Review

Front

What is a parallelogram?

Back

A parallelogram is a quadrilateral with both pairs of opposite sides parallel.

Front

What conditions must be met for a quadrilateral to be classified as a parallelogram?

Back

A quadrilateral is a parallelogram if both pairs of opposite sides are congruent, both pairs of opposite sides are parallel, or one pair of opposite sides is both congruent and parallel.

Front

What does CPCTC stand for in geometry?

Back

CPCTC stands for 'Corresponding Parts of Congruent Triangles are Congruent.' It is used to prove that corresponding angles and sides of congruent triangles are equal.

Front

What is the Angle Bisector Theorem?

Back

The Angle Bisector Theorem states that the angle bisector of an angle in a triangle divides the opposite side into segments that are proportional to the lengths of the other two sides.

Front

What is the Reflexive Property?

Back

The Reflexive Property states that any quantity is equal to itself, which is often used in proofs.

Front

What is the difference between SAS and ASA in triangle congruence?

Back

SAS (Side-Angle-Side) requires two sides and the included angle to be congruent, while ASA (Angle-Side-Angle) requires two angles and the included side to be congruent.

Front

How can you determine if two triangles are congruent using AAS?

Back

AAS (Angle-Angle-Side) states that if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, the triangles are congruent.

Front

What does it mean for two sides to be congruent?

Back

Two sides are congruent if they have the same length.

Front

What is the significance of diagonals bisecting each other in a parallelogram?

Back

If the diagonals of a quadrilateral bisect each other, the quadrilateral is a parallelogram.

Front

How do you solve for X in an equation?

Back

To solve for X, isolate X on one side of the equation using inverse operations.
