Geometry Semester Review 2024

Front

What is the SSS Postulate?

Back

The SSS (Side-Side-Side) Postulate states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to produce a new shape. Common transformations include translation, rotation, reflection, and dilation.

Front

What does it mean for a triangle's circumcenter to be sometimes located inside, outside, or on the triangle?

Back

The circumcenter is the point where the perpendicular bisectors of a triangle intersect. It can be inside the triangle (acute triangle), on the triangle (right triangle), or outside the triangle (obtuse triangle).

Front

How do you find a line perpendicular to another line?

Back

To find a line perpendicular to a given line, take the negative reciprocal of the slope of the original line and use the point-slope form of a line equation.

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never meet; they have the same slope but different y-intercepts.

Front

What is the SAS Postulate?

Back

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

Front

What is the ASA Postulate?

Back

The ASA (Angle-Side-Angle) Postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

Front

What is a reflection in geometry?

Back

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

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices. The sum of the interior angles of a triangle is always 180 degrees.
