**Perpendicular** **lines** **are** two or more **lines** that intersect at a **90**-**degree** angle, like the two **lines** drawn on this graph, and the x and y axes that orient them. **Perpendicular** **lines** **are** everywhere, not just on graph paper but also in the world around us...

**Perpendicular** **lines** meet each other at **90** **degrees**... that's the standard definition. Also, the product of the gradient of the two **lines** MUST **be** equal to -1, for both **lines** **to** **be** **perpendicular** to the other. The first pair: The gradients **are**

**Perpendicular** **lines** **have** **to** touch and meet at a **90** **degree** angle. They create right angles, which **are** **90** **degree** angles. Also, the equations and graphing of **perpendicular** **lines** work differently from that of parallel **lines**.

**Perpendicular** **lines** **are** **lines** that intersect at a **90** **degree** angle.

And so, that **is** **90** **degrees**, and that **is** **90** **degrees**. And I've constructed it that way. This top **line** **is** **perpendicular** horizontal. And then, I've dropped to vertical things. So, there **are** at **90** **degree** angles. And let me know setup some points.

Hence, if these two **lines** **are** **perpendicular**, then all four angles **are** **90** **degrees**. In the above figure, two **lines** AB and CD **are** **perpendicular** to each other; since all four angle made in this way **are** inclined at an angle of 90$^{\circ}$.

While **perpendicular** **lines** **are** **lines** that intersect at exactly **90** **degrees**.

But how can you determine if two **lines** **are** **perpendicular**? **Perpendicular** **lines** **have** a bit of a twist to them.

A) Two intersecting **lines** **are** **perpendicular** if and only if they form four 90* angles.

**Line** a **is** **perpendicular** to **line** c, as a result the angle marked **is** **90** **degrees**. For the **lines** a and b with transversal **line** c, A' = 90 as corresponding angles **are** equal in the case of parallel **lines**.

Two **lines** **are** **perpendicular** if one **is** at right angles to another- in other words, if the two **lines** cross and the angle between the **lines** **is** **90** **degrees**. If two **lines** **are** **perpendicular**, then their gradients will multiply together to give -1.

This **is** where I got stuck: Observe the slope of y = 15 **is** 0, and that means m = 0. For the other **line** **to** **be** **perpendicular**, m * m2 = -1. But for any m2, 0*m2 will never equal -1. I didn't know to use the other definition; their intersection **is** **90** **degrees**.
