## Are the lines AB and CD perpendicular?

Since product of slopes of the line AB and CD is equal to -1, **AB and CD are perpendicular to each other.**

## What is the slope of a line perpendicular to line CD?

The line CD if it is perpendicular to AB has a slope of **-1/0.5 or -2**

## Which line is perpendicular to AB?

Two distinct lines intersecting each other at 90xb0 or a right angle are called perpendicular lines. Here, AB is **perpendicular to XY because AB and XY intersect each other at 90xb0. The two lines are parallel and do not intersect each other. They can never be perpendicular to each other.**

## What Is the Relationship Between the lines AB and CD?

We write AB||CD to denote **AB is parallel to CD. We use little arrows on the two lines to indicate that they are parallel to each other. A transversal of two (or more) lines is another line that intersects the two lines. The angles Z1, Z2, Z7, Z8 are exterior angles because they are on the outside of lines AB and CD.**

## How do I know if my AB is perpendicular to a disc?

Note the slopes when the lines are at right angles to each other. So for example in the figure above, the line AB has a slope of 0.5, meaning it goes up by a half for every one across. The line CD if it is perpendicular to AB has a **slope of -1/0.5 or -2**

## What line shows in lines AB and CD?

parallel

## How do you determine if two lines are perpendicular?

Perpendicular lines intersect at right angles to one another. To figure out if two equations are perpendicular, **take a look at their slopes. The slopes of perpendicular lines are opposite reciprocals of each other.**

## How do you find the slope of a line perpendicular to another line?

Find The Slope Of A Perpendicular Line : Example Question #2 The perpendicular slope will be the opposite reciprocal of the original slope. Use the slope-intercept form (**y mx + b) and substitute in the given point and the new slope to find the intercept, b. Convert back to standard form of an equation: ax + by c.**

## What is the slope of CD and AB are they the same?

Since product of slopes of the line AB and CD is equal to -1, **AB and CD are perpendicular to each other.**

## What is the slope of a line perpendicular to line Q?

Parallel lines have equal slopes. thus slope of **AB is -3 and since CD is parallel to AB then the slopes are the same.**

## How many lines are perpendicular to AB?

one line

## What is the slope of the line perpendicular to AB?

The line CD if it is perpendicular to AB has a slope of **-1/0.5 or -2**

## Which line is perpendicular to the line?

Now let’s think about perpendicular lines. Perpendicular lines are lines that intersect at a 90-degree angle. So, for example, **line ST is perpendicular to line CD. So line ST is perpendicular to line CD.**

## What is the slope of AB?

Slope of Line AB ** (Rise/Run) -1.**

## What Is the Relationship Between the lines AB and CD provide a reason for your answer?

The lines AB and CD below never meet. Lines that never meet and are at a fixed distance from one another are called parallel lines. We write AB || CD. Parallel lines have the same direction, i.e. they form **equal corresponding angles with any line that intersects them.**

## What is true about the slopes of AB and CD?

**Parallel lines have equal slopes. thus slope of AB is -3 and since CD is parallel to AB then the slopes are the same.**

## What is the line AB and line CD are parallel lines?

Correct answer: Explanation: Lines AB and CD are parallel **based on the Alternate Exterior Angle theorem.**

## What does AB and CD mean?

ABCD just means that the two positive real numbers which are the lengths of those line segments are equal to each other. xafABu2245xafCD means that **the two line segments are congruent, where we define two line segments to be congruent if and only if they have the same length.**

## Is AB perpendicular to CD?

The segment AB is **perpendicular to the segment CD because the two angles it creates (indicated in orange and blue) are each 90 degrees. The point B is called the foot of the perpendicular from A to segment CD, or simply, the foot of A on CD.**

## How do you know if functions are perpendicular?

Since product of slopes of the line AB and CD is equal to -1, **AB and CD are perpendicular to each other.**

## How do you know if two pairs are perpendicular?

Perpendicular lines intersect at right angles to one another. To figure out if two equations are perpendicular, **take a look at their slopes. The slopes of perpendicular lines are opposite reciprocals of each other.**

## What type of lines are AB and CD?

Lines AB and CD are **parallel to each other. We use the symbol || to represent two lines being parallel. We write AB||CD to denote AB is parallel to CD.**

## How do you draw a line AB and line CDS are parallel lines?

Correct answer: Explanation: Lines AB and CD are parallel **based on the Alternate Exterior Angle theorem.**

## Why is AB parallel to CD?

The only thing that we logically conclude from the fact that AB is parallel to CD is that **angle v is equal to the angle, which is adjoining to x and equal to 180 deg x. We can conclude it if we continue the lines AB and CD to see angles equal to (180 deg v) and (180 deg x).**
