Summary: The number of sides of a regular polygon whose interior angle is 135° is 8.
To find the number of sides of a regular polygon with an interior angle of 135 degrees, use the formula (n-2)*180/n = 135. Solving for n gives you n = 8, so the polygon has 8 sides.
So the fraction of the complete angle is an angle of measure 135 degree is 3/8.
∴ The number of side is 18

Solution. An octagon has eight sides, so n = 8 n = 8 . Step 1: Using the formula a = ( n − 2 ) 180 ∘ 8 a = ( n − 2 ) 180 ∘ 8 : a = ( 8 − 2 ) 180 ∘ 8 = ( 6 ) 180 ∘ 8 = 135 ∘ .
The correct Answer is:27/20.
135 degrees is considered an obtuse angle.
Therefore, the given triangle is an Obtuse-angled triangle.
An interior angle of a regular polygon has a measure of 135°, it is an octagon.
135' is in the second quadrant, so our reference angle is 180'-135 ", or 45' .
A regular octagon will have all its sides equal in length. Each interior angle of a regular octagon is equal to 135°. Therefore, the measure of exterior angle becomes 180° – 135° = 45°. The sum of the interior angles of the octagon is 135 × 8 = 1080°.
Therefore, as a percent is 0.741%.
The simplified form of √135 in its radical form is 3√15. √135 is an irrational number.
Therefore, 75/135 simplified to lowest terms is 5/9.
A 135 degree angle is an OBTUSE angle. The miter for this corner is 67 1/2 degrees. That's easy to cut on your miter saw. Just set the saw at 22 1/2!
Answer:(a) 45 degrees- Acute angle ; (b) 90 degrees - Right Angle (c) 135 degrees - Obtuse Angle (d) 180 degrees- Straight Angle. Explanation: An angle is formed when two rays meet at a point. An acute angle is less than the right angle.
So slope, m=tan135o=−1.
In geometry, a dodecagon, or 12-gon, is any twelve-sided polygon.
Number of Diagonals = n(n-3)/2
In other words, an n-sided polygon has n-vertices which can be joined with each other in nC2 ways. Now by subtracting n with nC2 ways, the formula obtained is n(n-3)/2. For example, in a hexagon, the total sides are 6. So, the total diagonals will be 6(6-3)/2 = 9.
To calculate the number of sides of the polygon, divide 360 by the amount of the exterior angle. For example, if the exterior angle is 60 degrees, then dividing 360 by 60 equals 6, which is the number of sides the polygon has.
