A hexagon is a six-sided figure. Cut an equilateral triangle out of a piece of paper. Chop off little equilateral triangles at each tip of the triangle. What you have is a hexagonal piece of paper. Draw around it.
Yes. An equilateral triangle can be symmetrical because cut it straight down the middle and it will be symmertrical.
wrong. a triangle can have total of 180 deg inside anglesAny and every triangle will always have three internal angles which total 180 degrees.Equilateral triangles are special because all three angles are 60 degrees each.
Obviously!! That is when you cut the equilateral triangle into two with the help of a line running from the top part of the triangle and stands perpendicular to the base of the triangle.

Yes. An equilateral triangle can be symmetrical because cut it straight down the middle and it will be symmertrical.
Two triangles
An 8 sided octagon or a 4 sided rhombus can be formed depending on the size of the triangles cut from each corner.
no, it looks like an equilateral triangle with the top cut off.
Yes, they can. To demonstrate this draw a square on a sheet of paper. Draw a line diagonally from one corner to the one opposite. Cut along this line and you will have two triangles. Take them apart; if you put them together again in the right way you will have a square. Put together in different ways you can make an isosceles triangle or an equilateral parallelogram. If you do the same thing beginning with a rectangle, you will be able to reassemble the triangles to form a rectangle, isosceles triangle or a (non-equilateral) parallelogram.

A 30-60-90 right triangle
Cut it exactly down the middle, along its height, and put one piece aside. The remaining side is a right triangle. The slanting side of the right triangle is a whole side of the original equilateral triangle, the bottom is half of an original side, and the vertical line is the height of the original triangle. Now you have a right triangle and you know the lengths of two of its sides, so you use what you know about right triangles to find the length of the third side, which is the height of the original equilateral triangle. It turns out to be 0.866 times the side of the equilateral triangle. (rounded) Technically, that's (1/2) x (side) x sqrt(3)
Similar, YES. Congruent, NO.
