Geometry Semester 1 Test

Front

What is the distance formula in geometry?

Back

The distance formula is given by: d = √((x2 - x1)² + (y2 - y1)²), which calculates the distance between two points (x1, y1) and (x2, y2) in a coordinate plane.

Front

What is a line segment?

Back

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

Front

What is the definition of a ray?

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 the angles in a triangle?

Back

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

Front

What is the definition of a slope?

Back

The slope of a line is a measure of its steepness, usually represented as 'm' in the equation of a line (y = mx + b).

Front

How do you find the slope between two points?

Back

The slope (m) between two points (x1, y1) and (x2, y2) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What is the relationship between parallel lines and slopes?

Back

Parallel lines have the same slope and will never intersect.

Front

What is the relationship between perpendicular lines and slopes?

Back

Perpendicular lines have slopes that are negative reciprocals of each other (m1 * m2 = -1).

Front

What is an angle?

Back

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

Front

What is a right angle?

Back

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