There are three type of angles 1)right angle which is 90°2) acute angle which is less than 90° 3) obtuse angle is more than 90°but less than 180°

angles!

# data[].attributes.body
WE MUST LOOK OUT FOR THE POINTS AND THE LINE MUST BE STRAIGHT AND ACCURATE.

# data[].attributes.body
The line must be straight and accurate

# data[].attributes.body
If you are drawing an angle , you must draw in a straight . If you did not draw it in a straight line , you cannot find the actual degree for the angle .
90 degrees=RIGHT ANGLE
LESS than 90 degrees =ACUTE ANGLE
MORE than90 degrees =OBTUSE ANGLES

# data[].attributes.body
Examples of angles are right angles(90 degrees),acute angels(less than 90 degrees)and obtuse angles(more than 90 degrees but less than 180 degrees)

# data[].attributes.body
The examples of angles are a right angle (90 degrees) an obtuse angle (greater than 90 degrees) and a acute angle (lesser than 90 degrees)

# data[].attributes.body
right angle 90 degrees
obtuse angle 90 to 360 degrees
acute angle 1 to 89 degrees

# data[].attributes.body
the right angle is wrong as the angle is not a right angle but a acute angle.Labeled angle abc

# data[].attributes.body
if we want to draw an angle using a potractor , the line must be straight . We also must label the angle and the degree of the angle

# data[].attributes.body
A right angle is a 90 degree angle !

# data[].attributes.body
This is an example of an obtuse angle !

# data[].attributes.body
a obtuse angle is more than 90 degrees

# data[].attributes.body
this is an example of an acute angle

# data[].attributes.body
A acute angle must be lesser than 90 degrees

# data[].attributes.body
Right angle=90Degrees
Acute angle=less than 90 Degrees
Obtuse angle=more than 90 Degrees

# data[].attributes.body
The angle is wrong as there are no labels.

# data[].attributes.body
We need to look out for the correct scale to draw the angle and labelling them

# data[].attributes.body
The line we use to draw an angle must be a straight line.
And when we draw an angle we must label the letters and the degrees that the angle that we are drawing.
For example:

# data[].attributes.body
If you draw a Right Angle it must be 90 Degrees.
And if you draw a Acute Angle it must be smaller than 90 Degrees.
But if you draw a Obtuse Angle it must be bigger than 90 Degrees.

# data[].attributes.body
The angle below is wrong because it is lesser than 90 degree

# data[].attributes.body
Right Angle:  90°
Acute Angle: 90°-
Obtuse Angle: 90°+ 180°-

# data[].attributes.body
this is how to draw a right angle

# data[].attributes.body
Right Angle: 90 Degrees
Acute Angle: Less than 90 Degrees
Obtuse: More than 90 but less than 180

# data[].attributes.body
We need to look out for our angles and labeling.

The KEY 🔑 TERMS
Right angle,must be exactly 90 degrees
Obtuse,must be bigger than 90 degrees
Acute,smaller than 90 degrees
Complete turn,360 degrees
Half turn is 180 degrees

When drawing angles we need to look out for your lines and lable it.

Example:
Right angle:

KEY WORDS

Lines And Angles

Acute angle: Angles that is less than 90 °

Right angle: Angle that is exactly equal to 90 °

3. Obtuse angle: Angle that is greater than 90 ° and less than 180 °

Straight angle: Angle that is exactly equal to 180 °

Obtuse angle: Angle that is greater than 180 ° and less than 360 °

Complete (Full) angle: Angle that is exactly equal to 360 °

this diagram is wrong because there is no arrows to indicate angle.

# data[].attributes.body
As the diagram below it is wrong because the line is not straight and accurate.

The following is a wrong sample because there are no labels.

# data[].attributes.body
E.g. Key terms include outer and inner scale, centre of protractor etc.

# data[].attributes.body
Example - I must look out for the use of the correct scales (inner or outer)

# data[].attributes.body
Acute angle: Acute angle is less than 90 degree.
Right angle: Right angle is a angle that is exactly 90 degree.
Obtuse angle: Obtuse angle is greater than 90 degree but lesser than 180 degree.
Complete angle (full): Angle that is exactly at 360 degree.
Straight angle: Angle that is exactly 180 degree

Examples:
