**Construction of Angles:=**

<AOB =60°

OA place the protractor meter coincide ‘O’ to the left base line OA mark the protractor meter from left to right and against 90°, after that remove the protractor meter and draw the line point ‘O’.

**5th Standard Math’s Notes **

**Example :** Draw the angle 45°

Protractor meter are place on the panel Q center it coincide with Q is a base lone which is lying on PQ, R is against the protractor of 45°, remove the protractor meter and draw the line PQR=45°.

**Circles:-** Circles are drawn using bangles

The first figure are not using a line the figure is called circle closed. And the next two figure are drawn using the line.

**How to draw circle**

- Using bangle, take one blank sheet, draw the outline of the sheet draw closed circle is called circle.
- Draw the circle using compass : Compass is box in the placed an instruments in a geometry box, in that shape pencils and needles kept on point O and rotate the pencil from start to end complete one rotation back to start point.

Circles defines it is a closed curve whose points which are equal to the distance from a given point called center of circle.

**Different parts of circles:-**

**Radius**: joining the two points in a circle are called radius.

**Example**:

All the radii of circle are equal.

We draw the number of radii of the circle.

**Circumference**:- Distance around the circle is called circumference.

**Example**:

ABCA is lying on a circle.

**Chord**:- Combining two point in a circle draw a line of segment is called chord.

**Example**:-

AB, CD, EF, and GH are chords of circles.

**Diameters**:- Is a line of segment of combining two points and grouping through the center is called diameter.

Diameter= 2 * Radius

**Example**:- B to C is the circle of a diameter

**Interior and Exterior of Circle:-**The region inside the circle is called interior, The region outside the circle is called exterior.

**Example:**

A and B are Interior, C and D are Exterior.

**Semicircle:-**Diameter are divided into two equal parts, each part is called semicircle.

**Example:**

**Quadrant:-**Circles are divided into 4 equal parts, each part of the circle is called Quadrant. The circles are divided into 4 equal parts and it can be written as 1/4.

**Example:**

**Arc:-**The circumference of a circle is called arc.

**Example:**

**Concentric Circles:-**The circles which has same center but different radii is called concentric circles.

**Example:**
