What is the sum of all interior angles of regular hexagon?
Sum of Interior Angles of a Polygon
| Polygon Name | Number of Interior Angles | Sum of Interior Angles = (n-2) x 180° |
|---|---|---|
| Triangle | 3 | 180° |

| Pentagon | 5 | 540° |
| Hexagon | 6 | 720° |
What is the meaning of co interior angles?
Co-interior angles lie between two lines and on the same side of a transversal. In each diagram the two marked angles are called co-interior angles. If the two lines are parallel, then co-interior angles add to give 180o and so are supplementary.
What is the sum of two co interior angles?
Co-interior angles are the two angles that are on the same side of the transversal. Co-interior angles are the interior angles and it sums up to 180 degrees. It means that the sum of two interior angles, which are on the same side of transversal is supplementary.
How do you prove that co interior angles are equal?
(1) Suppose Co-interior property is known then the sum of angles on the same side is 180∘ if one angle is θ then the co-interior angle is 180∘−θ then the corresponding angles must equal by using linear pair property.
Do co-interior angles always add to 180?
If the transversal cuts across parallel lines (the usual case) then the interior angles are supplementary (add to 180°). So in the figure above, as you move points A or B, the two interior angles shown always add to 180°.
What are angles on the same line called?
In geometry, a transversal is a line that intersects two or more other (often parallel ) lines. In the figure below, line n is a transversal cutting lines l and m . When two or more lines are cut by a transversal, the angles which occupy the same relative position are called corresponding angles .
