Yes. for example to make a pyramid, you need 4 triangles and a square
A hexahedron is a 3D shape with 6 faces. It CAN be a prism whose base is a square. But that is only one example. It can also be a prism whose base is any quadrilateral. It can also be something like a pentagonal pyramid (i.e. the base is a pentagon and the sides are made up of 5 triangles.)
True
It's not that easy to answer because a straight angle is like a straight line and I think that it would be on either every or none of the shapes that I would know of. Any shape has a right, obtuse,or acute angle. So, I am guessing that no shapes have straight angles. or that a straight angle is in every angle which is not true.
True
No shape does. Euler's Formula (vertices + faces = edges + 2) holds true for all shapes. For the given figures, this means: 4 + 6 = 6 + 2 → 10 = 8 but 10 ≠ 8, so the combinations of 4 vertices, 6 edges and 6 faces given does not represent a shape.
Both are true there is an interdependance.
No. All four sided shapes are quadrilateral.
nonagon true but is there anymore shapes that have 9 sides?
That is true. Any material that converts to a solid state takes on the shape of the form used.
Most Shapes has many vertices & Sides. The answer is a '''Circle''' * * * * * Only partly true. Most '''WELL-STUDIED''' shapes have vertices and sides. Most shapes - in nature, for example, are irregular, "random" shapes.
A shape that doesn't have pairs of parallel sides is a circle. This is also true of ellipses and triangles.
There are many different shapes of which each have a different name. Pictures of these shapes cannot be drawn here to answer the question, but the can be described. The most common shapes that are used are squares, circles, and triangles. Squares are a box like shape with four equal sides, a true circle is a perfectly round shape, and the most common triangle shape has along bottom and two shorter sides that come together to make a point.
Yes * * * * * Not true! A circle is a 2-d shape that is not a polygon. A polygon must have sides that are straight lines. A 2-d shape need not have straight sides.
The answer is actually false Geometric shapes have definite shapes and the definition of amorphous is to be shapless
O
False. Every cross-sectional shape of a cone is not congruent.
