Geometry SOL Review #1

Front

What is the Law of Syllogism?

Back

The Law of Syllogism states that if 'p implies q' and 'q implies r', then 'p implies r'. It allows for drawing conclusions from two conditional statements.

How do you find the slope of a line given two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1). For points (10, 1) and (5, 2), the slope is m = (2 - 1) / (5 - 10) = -1/5.

What is the equation of a line parallel to y = -4x + 6?

Back

A line parallel to y = -4x + 6 will have the same slope of -4. The equation of the line passing through (2, -1) is y = -4x + 7.

What is a Perpendicular Bisector?

Back

A Perpendicular Bisector is a line that divides a segment into two equal parts at a 90-degree angle.

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

Define the slope of a line.

Back

The slope of a line is a measure of its steepness, calculated as the ratio of the vertical change to the horizontal change between two points on the line.

Front

What is the difference between a line and a line segment?

Back

A line extends infinitely in both directions, while a line segment has two endpoints and a finite length.

Front

What is the formula for the slope-intercept form of a line?

Back

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

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is an Angle Bisector?

Back

An Angle Bisector is a line that divides an angle into two equal angles.
