M218 Geometry Semester 1 Final Exam Review

Front

What is the formula to find the measure of an interior angle of a regular polygon?

Back

The measure of an interior angle of a regular polygon can be found using the formula: (n-2) * 180° / n, where n is the number of sides.

Front

How do you determine the length of a side in a triangle given two sides?

Back

Use the Pythagorean theorem (a² + b² = c²) for right triangles, or apply the triangle inequality theorem for other types.

Front

What is the definition of a rhombus?

Back

A rhombus is a quadrilateral with all four sides of equal length and opposite angles that are equal.

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

How can you identify the largest angle in a triangle?

Back

The largest angle in a triangle is opposite the longest side.

Front

What is an acute triangle?

Back

An acute triangle is a triangle where all three interior angles are less than 90 degrees.

Front

What is the measure of each interior angle of a regular hexagon?

Back

Each interior angle of a regular hexagon measures 120 degrees.

Front

What is the relationship between the angles in a right triangle?

Back

In a right triangle, one angle is exactly 90 degrees, and the sum of the other two angles is 90 degrees.

Front

What is the definition of complementary angles?

Back

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

Front

What is the definition of supplementary angles?

Back

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