Geometry Semester I Exam

Front

What is a line in geometry?

Back

A line is a straight one-dimensional figure that has no thickness and extends infinitely in both directions.

Front

What does it mean for two lines to be skew?

Back

Skew lines are lines that do not intersect and are not parallel; they exist in different planes.

Front

What is the definition of an angle?

Back

An angle is formed by two rays (sides of the angle) that share a common endpoint (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.

Front

What is a point in geometry?

Back

A point is a precise location or position in space, represented by a dot and has no size or dimension.

Front

What is the difference between intersecting lines and parallel lines?

Back

Intersecting lines cross at one point, while parallel lines never meet and are always the same distance apart.

Front

How do you find the measure of an unknown angle in a triangle?

Back

To find an unknown angle in a triangle, subtract the sum of the known angles from 180 degrees.

Front

What is a transversal line?

Back

A transversal line is a line that intersects two or more other lines at distinct points.

Front

What is the definition of a segment in geometry?

Back

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

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width (Area = length × width).
