MENU". By default, circle menu will be active on opening the software. Also it will

display the circles and lines, which are drawn, when you last used analytical

geometry module. Just click "Delete ALL" button to delete all the entities present

on the display area.

DRAW CIRCLE

This software supports 4 ways of input data for drawing a circle.

Using Centre and Radius

Using Centre and a Passing point

Using 3 Passing points

Using 2 Diameter points

1. Using Centre and Radius

By default, the first option, "Using Centre and Radius" is active on opening the

software with default values for centre (6, 3.1) and radius (1.5 units).

Now press "Draw Circle" button.

You will see the circle getting drawn in the display area. Any selected circle will

blink for around 4 seconds, for you to distinguish the circle among other circles, if

present. You will see the graph area automatically getting moved and zoomed

near to the circle. It is because, Auto Move and Auto Zoom options at the bottom

of the menu panel is selected.

You may also note that the "Circle Attributes" menu on the bottom of the menu

panel is getting active and it does the following.

It displays the radius of the circle as 1.5

It displays the mathematical equation of the circle as

25x + 25y -300x -155y + 1084 = 0When you deselect the option, "Try to show the equation with integers", itdisplays the equation in fractional form as

x + y -12x -6.2y + 43.36 = 0

It shows 3 buttons, namely, "SHOW", "HIDE" and "DELETE".

Click "HIDE" button. You will see that the drawn circle disappears from thedisplay area, but its attributes are retained and the drop down menu shows

it's status as "hidden". This feature is included to enable the user to hide any

drawn circle for better visibility of the rest of the entities in the display area.

Just click "SHOW" button, to make this circle visible again. Ensure that the

required circle is selected in the circle drop down menu.

are located at the bottom of the right side menu panel. By default, the check

boxes are checked. Assume that you draw (OR) view the attribute of any circle /

line. It is possible that the circle / line drawn is totally out of your current viewing

area. If the check box for Auto Move is in selected state, the display area

automatically moves to the location where you can see the circle / line. If auto

zoom is also selected, the software will try to zoom out to show the region of the

circle / line as well as your current viewing area. Please note that the auto zoomfunctions only when the auto move is enabled.

Refresh: Refresh button will help you refreshing the display area. It eliminates the

selected circle / line being shown in thicker lines. It displays everything in normal

colour and thickness.
