**This geometry worksheet will deal with Points, Lines, Rays, and Angles. Before diving into the geometry worksheet let’s recapitulate the terms that you already know.**

## What is a Point in geometry?

**A point **is a geometrical idea which is denoted by a dot. The point has a position but no magnitude. It is a basic unit of geometry that shows an exact location.

## What is a Line in geometry?

**A line can be defined as a collection of points that extends endlessly towards both directions. A line is generated arranging an infinite number of points side by side. A line has a length but no breadth. A line neither has a start point, nor an endpoint. A part of a line is called a line segment which has a start point and an endpoint. If A line segment starts at point A and ends at point B it can be denoted by point AB and the length of this line segment can be measured by a ruler or scale**.

There are two types of lines

**Straight line and****Curved line**

When a point moves without changing direction it traces a straight line. On the other hand if the point changes direction it will trace a curved line. A straight line is named by two points whereas a curved line is named by a minimum of three points.

Remember that, **Two-point P and Q can be joined by an infinite number of curved lines but there will be only one straight line joining them. The straight length will be the shortest distance between point P and Q.**

When two straight lines do not intersect even after extending infinitely in both directions and remain equidistant, they are called parallel lines. However, if they meet or intersect they are called intersecting lines.

Note that two straight lines can meet at one point only.

## What is a Ray in geometry?

In geometric concepts, A **ray** is a part of a line that starts at some point (or point of origin) and extends infinitely in one direction. So Ray has a start point but no endpoint**.** For example, A torchlight or one-way road can be considered as a Ray.

## What is an angle in geometry?

**When two straight lines meet at a point they form an angle. Angles are measured in degrees, using a protractor. **Refer to Fig. 2 and Remember the following information about angles:

- The common point where the lines meet is called the vertex and lines are called arms of sides of the angle.
- An angle that measures 90 degrees is called a right angle.
- An angle that measures less than 90 degrees is called an acute angle.
- An angle that measures more than 90 degrees but less than 180 degrees is an obtuse angle.
- An angle with 180 degrees measure is a straight angle.
- An angle that measures more than 180 degrees but less than 360 degrees is called a reflex angle.
- An angle that measures 360 degrees is called a total angle.
