Geometry Semester 1 Exam 2024

Front

What is the distance formula used to find the distance between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if they intersect at a right angle (90 degrees).

Front

What is a linear pair of angles?

Back

A linear pair of angles is formed when two adjacent angles are created by two intersecting lines, and they are supplementary (sum to 180 degrees).

Front

Define non-collinear points.

Back

Non-collinear points are points that do not all lie on the same straight line.

Front

What is the Angle Addition Postulate?

Back

The Angle Addition Postulate states that if point B lies in the interior of angle AOC, then the measure of angle AOB + the measure of angle BOC = the measure of angle AOC.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

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 difference between a ray and a line segment?

Back

A ray has one endpoint and extends infinitely in one direction, while a line segment has two endpoints and does not extend infinitely.

Front

What is the formula for finding the midpoint of a segment with endpoints (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2).
