How many faces are pentagons on a truncated icosahedron?
12 faces on a truncated icosahedron are pentagons. (The other 20 faces are hexagons.)
What is the linear relationship between number of sides and number of lines of symmetry?
If you're talking about convex polygons with equal sides (eg. equilateral triangles, squares, pentagons, hexagons, etc.), then the relationship is a very direct one. In those cases, there are as many lines of symmetry as there are points in the polygons. A triangle has three lines of symmetry, a square has four, a pentagon five, etc.
How many sides does a centagon have?
100 sides
How many congruent sides does a scalene triangle have?
0 sides
How many sides does a 1620 degree polygon have?
11 sides
How many sides do 4 decagons 5 dodecagons and 3 pentagons have altogether?
A decagon has 10 sides, a dodecagon 12, and a pentagon 5. So 4 decagons, 5 dodecagons, and 3 pentagons have 4*10 + 5*12 + 3*5 sides = 40 + 60 + 15 = 115 sides altogether.
How many sides do 5 decagons and 3 pentagons have altogether?
A pentagon has five sides, and a decagon has ten sides. So 3 pentagons and 5 decagons have (35)+(510) = 65 sides altogether
How many sides do 4 pentagons and 5 decagons have in all?
60
How many sides do 5 dodecagons and 4 pentagons have altogether?
A dodecagon has 12 sides, and a pentagon has 5 sides. So 5 dodecagons have 5*12 = 60 sides, and 4 pentagons have 4 * 5 = 20 sides, for a total of 60 + 20 = 80 sides.
How many sides do 2 pentagons and 5 decagons have in all?
There are (2*5) plus (5*10) = 60 sides
How many sides do 4 decagons 2 nonagons and 2 pentagons have altogether?
Each decagon has 10 sides, each nonagon has 9 sides and each pentagon has 5 sides. 4 decagons make 40 sides, 2 nonagons make 18 sides and 2 pentagons make 10 sides. When you add them all up together, you get 68 sides in total.
How many sides does a dodecagons?
They have 12 sides
How many sides do 4 decagons 3 dodecagons 1 nonagon and 3 triangles have altogether?
1*9 + 3*3 + 4*10 + 3*12 = 9 + 9 + 40 + 34 = 92
What are the kinds of dodecagon?
There are many ways of classifying decagons. There are convex or concave dodecagons. Or they can be classified as regular, equiangular-irregular, equilateral-irregular or fully irregular.
How many sides do 2 nonagons and 2 decagons have in all?
38 sides
How many sides do eleven pentagons have?
There are 11 times 5 = 55 sides in 11 pentagons.
How many sides do 1 pentagon and 4 do decagons have in all?
A pentagon has 5 sides, and a decagon has 10 sides. Therefore, 4 decagons would have (4 \times 10 = 40) sides. Adding the sides together, 1 pentagon and 4 decagons have a total of (5 + 40 = 45) sides.
