Geometry Semester Dec 2024

Front

What is an altitude in geometry?

Back

An altitude is a line segment from a vertex of a triangle perpendicular to the opposite side, representing the height of the triangle.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

Front

What is a point in geometry?

Back

A point is a specific location in space represented by a dot and has no dimensions.

Front

What does segment AB refer to?

Back

Segment AB refers to the part of a line that connects points A and B, including both endpoints.

Front

Which angles are congruent?

Back

Congruent angles are angles that have the same measure.

Front

What is a plane in geometry?

Back

A plane is a flat, two-dimensional surface that extends infinitely in all directions.

Front

What are complementary angles?

Back

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

Front

What is the difference between a line and a line segment?

Back

A line extends infinitely in both directions, while a line segment has two endpoints.

Front

What is an angle?

Back

An angle is formed by two rays that share a common endpoint, called the vertex.

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.
