The term “parallel” is also applied to Line segments and Rays when the lines they determine are parallel..
Some of the postulates we use often are:
The line containing any two points in a plane lies wholly in that plane. An angle has only one and only one bisector. Through any point outside a line, one and only one perpendicular can be drawn to the given line. A segment has one and only one mid point. Linear pair postulate: If a ray..
Rectangular coordinate system
The position of a point in a plane is determined by two coordinates. The method is as follows: Two mutually perpendicular lines (straight lines) XX' and YY' are drawn as shown in the figure. These straight lines are termed as coordinate axes, the one (usually drawn horizontally) is called the x-axi..

Two adjacent angles are said to form a linear pair of angles, if their non-common arms are two opposite rays. Recall adjacent angles. Now observe the pairs of angles in the figure. ..

Introduction - Recall that if two straight lines are not parallel, they meet at a point when produced. Observe lines l and m which meet at a point (O). In the diagram, l and m are called intersecting lines. O is called the point of intersection. Similarly two line segments or two rays may..

This is my favorite tutoring ever. i might say that to others to, but this tutoring has thought me the most from any tutorings!! -Ashlyn
I uploaded a worksheet and I wanted to follow it with the tutor so I could learn the technical parts. It took just a few minutes to get the understanding of what I needed with the tutor. I even get through all the examples on the sheet in 25 minutes that we were focused on it.
I learned a lot with this tutor. she was great at explaining the basic of chemistry. I have no questions left for the day. But I have lot to know from my tutor
The tutor really touched the right methods and formulas that would help me the most as well as a helpful practice sheet to test my knowledge of the subject. Great work!
