What is the interior angle measure of a regular pentagon?
108 degrees
Correct answer: where is equal to the number of sides of the regular polygon. The measure of one interior angle of a regular pentagon is 108 degrees.
What is the measure of each interior angle of a regular octagon?
135 degrees
Because the octagon is regular, all of its sides and angles are congruent. Thus, the measure of each angle is equal to the sum of its angles divided by 8. Therefore, each angle in the polygon has a measure of 1080/8 = 135 degrees.
What is the measure of an interior angle of a regular Pentadecagon?
156°
Pentadecagon
| Regular pentadecagon | |
|---|---|
| Symmetry group | Dihedral (D15), order 2×15 |
| Internal angle (degrees) | 156° |
| Dual polygon | Self |
| Properties | Convex, cyclic, equilateral, isogonal, isotoxal |
What is the measure of each interior angle of a regular hexagon?
120 degrees
A hexagon has six sides, and we can use the formula degrees = (# of sides – 2) * 180. Then degrees = (6 – 2) * 180 = 720 degrees. Each angle is 720/6 = 120 degrees.
How many interior angles does a Heptagon have?
seven
In geometry, a heptagon is a seven-sided polygon or 7-gon….Heptagon.
| Regular heptagon | |
|---|---|
| Internal angle (degrees) | ≈128.571° |
| Dual polygon | Self |
| Properties | Convex, cyclic, equilateral, isogonal, isotoxal |
What is the measure of an interior angle of a nonagon?
140°
Nonagon/Internal angle
What is the measure of an interior angle of a regular nonagon?
140 degrees
All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1260 degrees (from above)… And there are nine angles… So, the measure of the angle of a regular nonagon is 140 degrees.
What is the measure of an interior angle of a regular Nonagon?
How many interior angles does a Nonagon have?
9 angles
A nonagon consists of 9 angles. The sum of angles of a nonagon is 1260°.
