Some facts about equilateral triangles:
- all 3 sides are of the same length (that's what equilateral means)
- all 3 angles are the same size - 60 degrees because the 180 degrees in the triangle are shared out equally
- the shape has order 3 rotation symmetry (meaning there are 3 position into which you can rotate the shape to get the same view)
- the shape has 3 lines of symmetry

Does an equilateral triangle have only 3 congruent sides?
Yes. All equilateral triangles have 3 congruent sides. To know that it's an equilateral triangle the partial part of the word equilateral "equil" and "equal" mean the same thing except that "equil"is used in a word to tell that it's an equilateral triangle.
Prove that two equilateral triangles are always similar?
Two triangles are similar if: 1) 3 angles of 1 triangle are the same as 3 angles of the other or 2) 3 pairs of corresponding sides are in the same ratio or 3) An angle of 1 triangle is the same as the angle of the other triangle and the sides containing these angles are in the same ratio. So if they are both equilateral, then they both have three 60 degree angles since equilateral triangles are equiangular as well. Then number 1 above tell us by AAA, they are similar.
Which statement about squares and equilateral triangles are true?
Both are regular polygons
What is the area of an equilateral triangle with an apothem of 5cm?
5.7735 cm is the length of a side so 1/2 x base x Height should give you an answer. Remember, the apothem makes two mirrored 30 60 right triangles...Pythagoras will tell you how to find the hypotenuse...that will be the unknown side of the equilateral.
Tell you the shape consisting of eight triangles?
Octagon is consisting 8 triangles.
How do their areas triangles compare?
I'll be happy to help you, but in order for me to compare the areas of those triangles, you have to tell me the areas of those triangles.
Each side of an equilateral triangle is 32 centimeters What is the approximate height h of the triangle?
Well, what does an equilateral triangle tell you? Each of its angles are 60 degrees. If you split an equilateral triangle in half, you will have two right triangles, which you use the Pythagorean Theorem to solve. You know the base (a), 32cm divided by 2 equaling 16cm (because you split the equilateral triangle in half). You know the hypotenuse (c), 32cm. To find the height (b), you will need to use the Pythagorean Theorem: c2 = a2 + b2 for one of the right triangles. Now, fill in the known information.c2 = a2 + b2322 = 162 + b2322 - 162 = b21024 - 256 = b2768 = b2Take the square root (sqrt) of both sides.sqrt 768 = sqrt b216√3 centimeters, or 27.71 cm.
All of my 4 faces are triangles what is it?
