51.428571° is the measure of an exterior angle of a heptagon. You can always find the measurements of a regular polygon by dividing 360 by the amount of sides.
The 7 exterior angles of a septagon or a heptagon add up to 360 degrees
the interior angle is about 128.571428 the exterior angle is about 51.4285
An exterior angle is 360/7 = 51.4286 degrees. So interior angle is 180 - exterior angle = 128.57 degrees (approx).
360/7 = 51.43 degrees (approx).
It can have any value in the range (0, 360) degrees - other than 180 deg.
51.4 - 51.5
The exterior angle of a n-gon is 360/n degrees. So for a heptagon, the exterior angle is 360/7 = 51.429 degrees.
The 7 exterior angles of an heptagon add up to 360 degrees The 7 interior angles of an heptagon add up to 900 degrees
That depends on the type of triangle it is but if it's an equilateral triangle then its exterior angle is greater than that of a regular heptagon
It is the equilateral triangle that has the largest exterior angle of 120 degrees
