3 because equilateral triangles are triangles that have 3 congruent sides.
All triangles have 3 sides.
3*10 = 30 sides.
All triangles have exactly 3 sides. That is what the word triangle means, a geometrical figure having 3 angles and 3 sides. Always 3.
In common with all triangles it has 3 sides.
A pentagon has 3 triangles and 5 sides

3*10 = 30 sides.
A triangle has three sides, so six triangles have 6 * 3 = 18 sides altogether.
All triangles have exactly 3 sides. That is what the word triangle means, a geometrical figure having 3 angles and 3 sides. Always 3.
In common with all triangles it has 3 sides.
All triangles have 3 sides and 3 vertices.
There's 5 triangles but till 3 sides in each, in Hectagon is 8 sides and the 3 Decagons are still 10 sides on it.
6 triangles is 18 and 3 squares is 12 18 +12 ------- 30
There are ten sides in a decagon and three sides in a triangle. So in 3 decagons and 5 triangles there are 3*10 + 5*3 = 30 + 15 = 45 sides altogether.
3*9 = 27 sides
