square
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.
What shape has 3 squares and 2 triangles?
The shape that has 3 squares and 2 triangles is a pentagon. A pentagon is a five-sided polygon with five angles. In this case, the pentagon is made up of 3 squares, each contributing 4 sides, and 2 triangles, each contributing 3 sides. Therefore, the total number of sides in this pentagon would be 3 squares (12 sides) + 2 triangles (6 sides) = 18 sides.
An octahedron is made up of how many triangles?
Oh, dude, an octahedron is made up of 8 triangles. Yeah, like, imagine a stop sign, but in 3D and with triangles instead of sides. So, if you're ever in a geometry showdown and someone asks you how many triangles are in an octahedron, you can confidently say 8 and totally impress them.
What shape has 3 sides but is not a triangle?
There is no shape that is made up 3 sides that is not a triangle. Any shape that is made up of 3 sides is classified as a triangle no matter what shape or size it is.
