Mr. White: Geometry A Final Exam

Front

What is the AAS triangle congruence theorem?

Back

AAS stands for Angle-Angle-Side, which states that if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.

Front

What type of angle is formed when it measures exactly 90 degrees?

Back

A right angle.

Front

How do you find the length of a side in a triangle?

Back

Use the Pythagorean theorem (a² + b² = c²) for right triangles, or apply the Law of Sines or Law of Cosines for non-right triangles.

Front

What is the slope of a line in the equation y = mx + b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

What are vertical angles?

Back

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

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is a linear pair of angles?

Back

A linear pair consists of two adjacent angles that form a straight line, and their measures add up to 180 degrees.

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices.

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 difference between acute and obtuse angles?

Back

An acute angle measures less than 90 degrees, while an obtuse angle measures more than 90 degrees but less than 180 degrees.
