Geometry H Part 2: Final Review Sem 1

Front

What is the Reflexive Property in geometry?

Back

The Reflexive Property states that any geometric figure is congruent to itself. For example, segment AB is congruent to segment AB.

Front

What is the Symmetric Property in geometry?

Back

The Symmetric Property states that if one figure is congruent to another, then the second figure is congruent to the first. For example, if triangle ABC is congruent to triangle DEF, then triangle DEF is congruent to triangle ABC.

Front

What is the definition of the Orthocenter of a triangle?

Back

The Orthocenter is the point where the three altitudes of a triangle intersect.

Front

What is the definition of the Circumcenter of a triangle?

Back

The Circumcenter is the point where the perpendicular bisectors of the sides of a triangle intersect, and it is the center of the circumcircle.

Front

What is the definition of the Incenter of a triangle?

Back

The Incenter is the point where the angle bisectors of a triangle intersect, and it is the center of the incircle.

Front

What is the definition of the Centroid of a triangle?

Back

The Centroid is the point where the three medians of a triangle intersect, and it is the center of mass of the triangle.

Front

What does the notation PRC represent in triangle congruence?

Back

PRC indicates that triangle PQR is congruent to triangle RST.

Front

What is the purpose of a proof in geometry?

Back

A proof is a logical argument that demonstrates the truth of a geometric statement using definitions, properties, and previously established theorems.

Front

How do you rotate a point 180° about the origin?

Back

To rotate a point (x, y) 180° about the origin, the new coordinates will be (-x, -y).

Front

What is the formula for finding the distance between two points (x1, y1) and (x2, y2)?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).
