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.
Are pyramids made up from equilateral triangles?
The Great Pyramids at Giza are, but the Meso-Americans were truncated.
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.
What is a closed figure made up of straight line segments?
triangles , polygons ,quadrilaterals
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 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.

What is the name of a quadrilateral made from two identical isosceles triangles?
In general, a parallelogram. But if the triangles are joined along their odd side, a rhombus.
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.
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.
Is a regular pentagon made up of 5 isosceles triangles?
It can be, if all the vertices of the pentagon are joined to its centre. But if they are joined to any other point, it will not be.

Inscribed triangles in a rectangle are identical right triangles but they are rotated 180 relative to each other.
Can all 4 sided figures be made from 2 triangles why?
Yes. You can always draw a "diagonal" line between opposite corners of any four-sided figure. Then, cutting along that line, you wind up with two triangles out of which the figure could have been made.
