### DAV Class 4 Maths Chapter 6 Worksheet 1 Notes

Point:
A point is an exact location.

Line segment:
Let A and B are two points.

The straight path from A to B is called the line segment AB. It is denoted by $$\overline{A B}$$.

Line:
A line is an endless straight path that extends in both directions. A line has no end points. It is denoted by $$\overline{A B}$$.

Ray:
A ray is a straight path having one end point and extending endlessly in one direction only. It is denoted by $$\overline{A B}$$.

Acute Angle:
The angle whose measure is less than 90° is called an acute angle.

Obtuse Angle:
The angle whose measure is more than 90° is called an obtuse angle

Right Angle:
The angle whose measure is equal to 90° is called as right angle.

Straight Angle:
The angle of 180° is called as straight angle.
