by using a ruler
Use a protractor.
the measure of the inscribed angle is______ its corresponding central angle
An exterior angle of a regular polygon and its corresponding interior angle = 180° If an exterior angle is 1/8 of the interior angle (A) then A + A/8 = 180 : 9A = 1440 : A = 160 Each exterior angle is thus 180 -160 = 20° The number of sides = 360 ÷ exterior angle = 360 ÷ 20 = 18
The only way to do it is to measure the angles, There is no formula that will give you the measure of an interior angle of any shape unless it happens to be regular. And there is nothing in the question to suggest that the shape might be regular.
When a polygon is regular, each exterior angle is equal to the other exterior angles. Since the sum of all the exterior angles is 360 degrees, if you divide 360 by the measure of one exterior angle, you will get the number of sides. If you instead have the measure of an interior angle, simply calculate (180 - interior angle measure) to find the measure of the exterior angle, and use the above paragraph.
Providing that it is a regular hexagon then each exterior angle will measure 60 degrees
each measure of the angle at point h has a measure of
It is: 360/5 = 72 degrees for each exterior angle and each interior angle will be 108 degrees
Bing it
Each interior angle measures 162 degrees.
Each exterior angle of a regular octagon measures 45 degrees
The measure is 360/9 = 40 degrees.
8100
128.571428 repeating
72 degrees
that's geometry so the formula to find the measure of each interior angle of a regular polygon is: Ia=stands for internal angle Ia=(n-2)180 ---------- n that's the formula.
In general, you will need to use a protractor and measure them.
