Welcome to today's class.
Lines and Angles - Lesson 3
Learning outcomes :
(a)Are all perpendicular lines intersecting lines ?
Yes
(b)Are all intersecting lines perpendicular ?
No
Do Try These - Page 104
Transversal
A transversal is a line that passes through two lines in the same plane at two distinct points.
Do Try These Page 105
How many transversals can you draw to two given lines?
The answer is infinite number of transversals.
The transversal divides the plane into 2 parts
area between the parallel lines (interior)
area outside (exterior)

Lines and Angles - Lesson 3
Learning outcomes :
- identify the given pair of lines as parallel or intersecting
- identify a transversal
- generalize the relationship between the angles formed by a pair of parallel lines
Intersecting Lines :
Point of intersection.
When two or more lines cross each other in a plane, they are called intersecting lines.
The intersecting lines share a common point, which exists on all the intersecting lines, and is called the point of intersection.
Here, lines P and Q intersect at point O, which is the point of intersection.
Yes
(b)Are all intersecting lines perpendicular ?
No
