A line segment is a part of a line that is bounded by two distinct endpoints.

Front

What is a point in geometry?

Back

A point is a precise location or position in a two-dimensional or three-dimensional space, represented by a dot.

Front

What is an obtuse angle?

Back

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

Front

What are perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

What is the difference between parallel lines and perpendicular lines?

Back

Parallel lines never intersect and are always the same distance apart, while perpendicular lines intersect at a right angle.

Front

How do you identify a line in a diagram?

Back

A line is typically represented as a straight path that extends infinitely in both directions, often depicted with arrows at both ends.

Front

What is a ray in geometry?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

Front

What is the sum of angles in a triangle?

Back

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

Front

What is a straight angle?

Back

A straight angle is an angle that measures exactly 180 degrees.

Front

What is a right angle?

Back

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