Geometry Semester 1 Final Exam 1-15

Front

What is the definition of a coordinate point in a Cartesian plane?

Back

A coordinate point is defined by an ordered pair (x, y) where 'x' represents the horizontal position and 'y' represents the vertical position on the Cartesian plane.

Front

What does the acronym SSS stand for in triangle congruence?

Back

SSS stands for 'Side-Side-Side', which is a criterion for triangle congruence stating that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What does the acronym SAS stand for in triangle congruence?

Back

SAS stands for 'Side-Angle-Side', which is a criterion for triangle congruence stating that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What does the acronym ASA stand for in triangle congruence?

Back

ASA stands for 'Angle-Side-Angle', which is a criterion for triangle congruence stating that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

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

Back

Front

What is the definition of an angle?

Back

An angle is formed by two rays (sides of the angle) that share a common endpoint (the vertex of the angle).

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

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 definition of a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What is the definition of a supplementary angle?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.
