What else can I help you with?
Are the internal angle and external angle of a polygon supplementary?
yes.
What is the external angle of a triangle?
360 degrees take away the internal angle
What is the external angle if the internal angle is 135 degree?
180-135 = 45 degrees
What is the internal angle of undecagon.?
we have eleven sides in external and internalangle..
How many sides does a polygon have when its internal angles are 150 degrees?
Internal angle = 150° → external angle = 360° - 150° = 30° number of sides = 360 ° ÷ external angle = 360° ÷ 30° = 12 It has 12 sides.
What is the internal angle of regular undecagon?
we have eleven sides in external and internalangle..
What is the angle between two adjacent sides of a 12 sided regular polygon?
Any polygon has a total external angle of 360 degrees This is split between all the angles around the shape, n the case of a regular polygon they would also be equal, so the external angles would be 360 / 12, which is 30. However you need to know the internal angles As you know there are 180 degrees in a straight line, the external angle is 30 degrees as explained above, so the internal angle is 180 - 30, which is 150 degrees
Why do rain drop undergo total internal reflection?
Simple - they don't. TIR occurs when there is no external angle that corresponds to the internal angle. Since the light has to originate outside of the raindrop, and the geometry is the same every time the light crosses the boundary, there is always an external angle corresponding to the internal one. Anybody who claims otherwise is confusing "*AN* internal reflection" with "total internal reflection."
In Internal or external tapers on a turret lathe can be turned by?
In a turret lathe, internal and external tapers can be turned using a taper attachment or by setting the tool at an angle relative to the workpiece. For external tapers, the tool can be adjusted to cut at the desired taper angle while rotating the workpiece. Internal tapers can be achieved by using a boring tool set at the correct angle or by adjusting the tool post position. This allows for precise taper machining on both internal and external surfaces.
How many angles are there in alphabet 'v'?
There are two angles in the letter V. An acute angle (internal) and a reflex angle (external).
Is a hexagon a angle?
no, the internal angles of a hexagon are 120 degrees and the external angles are 60 degrees.
What are external angles?
An external angle is the angle between the outside of one side and the extension of the adjacent line. They all add to 360o.
