原句"A regular polygon has all its sides equal."的if-then形式需要体现条件与结论的逻辑关系。原句可拆解为:若一个多边形是正多边形(条件),则它所有边相等(结论)。 **选项分析**: - **A**:"If a polygon is regular, then it has all its sides equal." ...
All sides must be straight, and they must all connect. There are regular and irregular polygons. With regular polygons, all the sides are equal, as are the angles. Regular polygons include equilateral triangles, squares and many other shapes. Read Regular Polygon | Definition, Sides & Types...
The words for polygons with sides (e.g., pentagon, hexagon, heptagon, etc.) can refer to either regular or non-regular polygons, although the terms generally refer to regular polygons in the absence of specific wording. A regular -gon is implemented in the Wolfram Language as Regular...
Regular polygon formulas: sides, area, perimeter, angles How to use this polygon calculator — an example With this polygon calculator, you can find the essential properties of any n-sided regular polygon. Whether you are looking for the area of a heptagon or the angles in a decagon, you'...
All of its sides are straight; none of its sides are curved. There are also no gaps in the sides. Polygons can be laid side to side with other polygons and when sized to match neighboring polygons, no spaces or gaps are seen. Polygons arranged in a square...
What is the measure of each angle in a regular polygon with 14 sides? if necessary, round your answer to the nearest tenth. Find the sum of the measures of exterior angles of a regular pentagon. One interior angle of a pentagon has a measure of 120 degrees. The other four interior an...
How many sides does a regular dodecagon have? it has twelve sides What is the name of a 12 sided pentagon? Dodecagon. A pentagon has five sides, a polygon with 12 sides is a dodecagon. A dodecahedron has 12 regular facets. If each side of a regular dodecagon measures 7 in What is th...
What is the number of sides for a regular polygon with interior and exterior angles in a 72:2 ratio? A regular polygon has six sides. The measure from the center of the polygon to a vertex is 4 m. What is the area of the regular polygon?
Perimeter of a Regular Polygon P = n a (1) where P = perimeter (m, ft ..) n = number of sides a = length of side (m, ft, ..) Area of a Regular Polygon A = n a r / 2 = n r2tan(Θ) = n R2sin(2 Θ) / 2 (2) ...
