What is an icosohedron?
a geometric shape made up of 20 triangles. :)
What are Multiple triangles?
A triangle that can be made in more than one way
What 3D figure has eight triangles?
An octagonal pyramid has eight triangles on an octagonal base. An octahedron can also be made by putting a square pyramid on another inverted square pyramid. This shape has just eight triangles and no others.
How many vertices does a tetahedron have?
a tetrahedron is made of four triangles and has 4 vertices.
What combination of shapes that you could use to make a hexagon?
There are an infinite number of options. Even sticking with polygons with sides of the same measure, a hexagon can be made from 6 equilateral triangles, or 4 eq triangles and a 60 degree rhombus, or 2 eq triangles and 2 60-deg rhombi, or 3 60-deg rhombi. Each of the equilateral triangle could be made from smaller shapes. Eg four equilateral mini-triangles to make 1 triangle. Or 2 mini-triangles and 1 mini-rhombus or 2 60-deg mini-rhombi. And then each of those mini triangles could be made up of smaller micro-shapes. And so on ...
What is the formula to determine how many parallelograms there are in an isosceles triangle made up of smaller isosceles triangles of the same size?
An isosceles triangle can be divided into 4 smaller, identical isosceles triangles. Each of these can then be divided into 4, and each of them ... So, the answer to the question is infinitely many.
How many triangles made by diagonal in a quadrilateral?
8
Are pyramids made up from equilateral triangles?
The Great Pyramids at Giza are, but the Meso-Americans were truncated.
What shape is made up from 4 triangles?
It would depend on the triangles, but assuming they were equilateral or isosceles, a trapezoid if alternated in a line.
What triangles will form a kite?
A kite is a quadrilateral with two distinct pairs of adjacent sides that are congruent. In terms of triangles, a kite can be formed by two congruent right triangles sharing a hypotenuse, or by two congruent isosceles triangles sharing a base. Additionally, a kite can also be formed by combining two congruent scalene triangles with a shared side.
What is the formula to determine how many parallelograms there are in an isosceles triangle made up of 9 smaller but equally sized isosceles triangles?
There are normally no parallelograms within an isosceles triangle unless you put them there yourself.
What kind of four sided figure is made using two equilateral triangles?
Rohmbus is a four sided figure (quadrilateral) that is made up of two equilateral triangles
Can all 4 sided shape be made by two right angled triangles?
Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.
How many triangles can a 20-gon be made into?
20 isosceles triangles with each base being a side of the 20-gon, and the opposite vertices at the center of the polygon.
What shape is made out of two congruent triangles?
If you have 2 EQUILATERAL triangles, and you stack them on their respective hypotenuses, the result: SQUARE. If you have 2 ISOSCELES triangles, and you stack them on their respective hypotenuses, the result: RECTANGLE. If you have 2 OBTUSE triangles, and you stack them on their respective hypotenuses, the result: PARALLELOGRAM.
Vincent drew a line from one coner of a rectangle to another corner to make 2 triangles describe the 2 triangles he made?
Inscribed triangles in a rectangle are identical right triangles but they are rotated 180 relative to each other.
What percent of the trapezoid is a triangle?
50% because a trapezoid is made from 2 triangles
