Angle ( ေထာင္႔ )

Angle : Right Angle , Acute Angle , Obtuse Angle

မ်ဥ္းေျဖာင္႔ႏွစ္ခု ေတြ႕ဆံုေသာအခါ Angle ျဖစ္လာမည္ ။
မ်ဥ္းေျဖာင္႔တစ္ခုသည္ အျခားမ်ဥ္းေျဖာင္႔တစ္ခုေပၚတြင္
ေဘးခ်င္းယွဥ္လ်က္ ေထာင္႔ႏွစ္ခုျဖစ္ေစရန္ ေတြ႕ဆံုလိုက္ပါ ။
ထိုအခါ အေျခအေန ႏွစ္မ်ဳိး ျဖစ္လာႏိုင္သည္ ။







ေဘးခ်င္းယွဥ္လ်က္ ေထာင္႔ႏွစ္ခု မတူၾကေခ် ။

Acute Angles 

ငယ္ေသာေထာင္႔ကို Acute Angle ဟု ေခၚပါတယ္ ။

An acute angle is an angle measuring between 0 and 90 degrees.

Example:

The following angles are all acute angles.  

Obtuse Angles

ၾကီးေသာေထာင္႔ကို  Obtuse Angles ဟု ေခၚပါတယ္ ။

An obtuse angle is an angle measuring between 90 and 180 degrees.

Example:

The following angles are all obtuse.

Right Angles

A right angle is an angle measuring 90 degrees.

Two lines or line segments that meet at a right angle are said 

to be perpendicular. Note that any two right angles are

supplementary angles (a right angle is its own angle supplement). 

Example:

The following angles are both right angles.
