This is how large 1 Degree is . 120 Degree Angle. a 90° angle, called a right angle, is made of two perpendicular lines. 2. This is called 360 deg, single phase AC. Maths MCQs for Class 8 Chapter Wise with Answers PDF Download was Prepared Based on Latest Exam Pattern. There are angles with less than a 90 degree bend leaving the legs more open than 90 degrees. Basic rotations. Join now. One Degree. Log in. Additionally, among the curves of constant width, the Reuleaux triangle is the one with both the largest and the smallest inscribed equilateral triangles. These smaller units, however, can only be measured with high-precision instruments. Construction of angle of 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165 and 180 degree newIt is written 130 degree in place of 135 degree by mistake. 4 years ago. It is formed when the two line segments make an angle of 90 degrees after joining. Thanks again! College. Question 387637: If each interior angle of a regular polygon measures 120 degrees then what would be the equation to find the number of sides,n in this polygon? 2012-05-02 12:55:30 2012-05-02 12:55:30. An acute angle is an angle measuring between 0 and 90 degrees. A triangle has angle measures 15 degree, 120 degrees, and 45 degrees. So for example, 60° and 120° are supplementary angles. Answer. On other pages there are instructions for constructing angles of 30°, 45°, 60° and 90°. Explanation: The angle between the isometric axes is 120 degrees if any line is parallel to it then those are called isometric lines. An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. One could argue that this is the same as a zero-sized angle. Add that to the 90° we already marked off, and we have about a 120° angle. In fact, it is the same as a line. Now, suppose the generator has two magnets and two coils placed equidistantly, then the flicker rate is increased, it is 2-phase , 360/2=180 degrees AC. Source(s): hope this helps. Looking at the remaining angle, we can tell that it's definitely less than 45°, maybe about a 30° angle. You also didn't write what the angle is called, "let say..." $\endgroup$ – DonAntonio Oct 30 '13 at 17:23 $\begingroup$
