Geometry Chapter 4 Review

Front

What does CPCTC stand for?

Back

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

What is the rule for rotating a point 180° in the coordinate plane?

Back

The rule for rotating a point (x,y) 180° is (x,y) → (-x,-y).

Front

What is the correct congruence statement for triangles TUV and UVE?

Back

The correct congruence statement is ∆VUT ≅ ∆UVE.

Front

What is the HL Theorem in triangle congruence?

Back

The HL Theorem states that if a triangle is a right triangle and the hypotenuse and one leg are congruent to the corresponding parts of another right triangle, then the two triangles are congruent.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for 'Angle-Angle-Side.' It is a postulate used to prove that two triangles are congruent if two angles and a non-included side are known.

Front

What is the definition of an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

What is the SAS postulate?

Back

The SAS postulate states that if two sides of one triangle are congruent to two sides of another triangle and the included angle is also congruent, then the triangles are congruent.

Front

What is the difference between ASA and AAS?

Back

ASA (Angle-Side-Angle) requires two angles and the included side to be congruent, while AAS (Angle-Angle-Side) requires two angles and a non-included side to be congruent.

Front

What is the definition of a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.
