Module 6 Review and Midterm Review Flashcardizz Geometry

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a theorem used to prove that two triangles are congruent if two angles and a non-included side are known.

Front

What is the formula to find the endpoint of a segment given one endpoint and the midpoint?

Back

If one endpoint is (x1, y1) and the midpoint is (xm, ym), the other endpoint (x2, y2) can be found using the formulas: x2 = 2*xm - x1 and y2 = 2*ym - y1.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent.

Front

What is the significance of the congruence statement PRC?

Back

The congruence statement PRC indicates that triangle P is congruent to triangle R and C, showing the order of corresponding vertices.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, including translations, rotations, reflections, and dilations.

Front

Define the term 'midpoint' in geometry.

Back

The midpoint of a segment is the point that divides the segment into two equal parts.

Front

What is the difference between corresponding angles and alternate interior angles?

Back

Corresponding angles are in the same position on parallel lines cut by a transversal, while alternate interior angles are on opposite sides of the transversal and inside the parallel lines.

Front

What does the term 'reflection' mean in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

Explain the concept of congruence in triangles.

Back

Two triangles are congruent if they have the same size and shape, which can be proven using various congruence theorems like SSS, SAS, AAS, and ASA.

Front

What is the SAS congruence theorem?

Back

The SAS (Side-Angle-Side) theorem states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.
