Cut two boards at 22.5, they'll form a 135-degree angle. Think about it like this: if you cut two boards at 0 degrees(ie perpendicular to board), you get a 180 joint (straight line). if you cut two boards at 5 degrees, you get a 170-degree joint.
An obtuse angle 135-degree.
So the fraction of the complete angle is an angle of measure 135 degree is 3/8.
Summary: The number of sides of a regular polygon whose interior angle is 135° is 8.
Summary: An interior angle of a regular polygon has a measure of 135°, it is an octagon.
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!
So slope, m=tan135o=−1.
The correct Answer is:27/20.
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.
135' is in the second quadrant, so our reference angle is 180'-135 ", or 45' .
135 degrees is considered an obtuse angle.
If you think of it first as a 90o bend, then add a further 45o to it and - whoohoo - you get 135o.
In vertical position slope remains between 45 and 90 degrees and rotation may have any value from 0 to 180 degrees. (4) Overhead position. The plane of the workpiece is horizontal; welding is carried out from the underside, electrode pointing upward.
Place the protractor on the vertex of the original 90-degree angle and measure 135 degrees from the baseline. Mark this point and draw a line from the vertex through this mark. This new line forms a 135-degree angle with the baseline.
The regular polygon with an internal angle measurement of 135∘ is a regular octagon.
Therefore, the given triangle is an Obtuse-angled triangle.
