Geometry 1st Semester Exam - part 1

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

If two angles form a linear pair, what can be said about their measures?

Back

The measures of two angles that form a linear pair are supplementary, meaning they add up to 180 degrees.

Front

What is a plane in geometry?

Back

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

Front

What is the intersection of two lines?

Back

The intersection of two lines is a point, which is the location where the two lines meet.

Front

What are complementary angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

What is a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles formed when two lines intersect, and they are supplementary.

Front

What is the definition of a point in geometry?

Back

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

Front

What is a line in geometry?

Back

A line is a straight one-dimensional figure that extends infinitely in both directions with no endpoints.

Front

What is a ray in geometry?

Back

A ray is a part of a line that has a fixed starting point and extends infinitely in one direction.
