Any equilateral triangle has 3 sides of equal lengths and 3 equal interior angles of 60 degrees. 3*60 = 180 degrees.
In a square, you can find a multitude of triangles depending on how you draw them. For instance, if you consider triangles formed by connecting the corners of the square and points along the edges, the number increases significantly. If you simply count the triangles that can be formed using the square's vertices and midpoints, there are 8 distinct triangles. However, with more combinations and subdivisions, the total number of triangles can rise into the hundreds.
Find the area of the square and two triangles that compose the rhomboid.
A diagonal bisecting a square creates two identical right triangles. The diagonal is the hypotenuse of a right triangles, so its length is the square root of the sums of the squares on the opposite two sides.
In an octagon, there are 20 equilateral triangles. Each side of the octagon can form two equilateral triangles with the adjacent sides, resulting in 8 equilateral triangles. Additionally, the diagonals of the octagon can form 12 more equilateral triangles. Therefore, the total number of equilateral triangles in an octagon is 8 + 12 = 20.

Area = 0.5*base*perpendicular height
If a triangle is isosceles, then it is equilateral. To find the converse of a conditional, you switch the antecedent ("If ____ ...") and consequent ("... then ____."). (Of course, if not ALL isosceles triangles were equilateral, then the converse would be false.)
In effect an equilateral triangle is made up of two right angle triangles joined together so use Pythagoras' theorem to find the height:- 182-92 = 243 and the square root of this will be the height of the equilateral triangle which is about 15.588 cm
Easy way to work it out: Break the square down into four equilateral triangles, formed by the border of the square and two diagonal lines intersecting it. Each of those triangles will be right isosceles triangles, with their sides adjacent to the right angle each having a length that is equal to the radius of the circle. Their area then would be the square of that radius, divided by two (a = wh/2). Each of those four triangles then, has an area of 242 / 2. There are four of those triangles forming the square, so it's area would be 2 * (24cm)2, or 1152 cm2.
Any equilateral triangle has 3 sides of equal lengths and 3 equal interior angles of 60 degrees. 3*60 = 180 degrees.
the answer is pyramid
4 triangles and 1 square.
Find the area of the square and two triangles that compose the rhomboid.
Triangles you use : (base x perpendicular height) divided by 2. Parallelogram: you need to find the area of one of the side triangles, then double it (because there's two of them). Then find the area of the square in the middle, and add this to the area of the two triangles.
An equilateral triangle has 3 equal interior angles each of 60 degrees. There are two right angled triangles in an equilateral triangle. So we can use trigonometry to find the length of one side of the equilateral triangle then multiply this by 3 to find its perimeter. Hypotenuse (which is one side of the equilateral) = 15/sin 60 degrees = 17.32050808 17.32050808 x 3 = 51.96152423 Perimeter = 51.96152423 units.
