How are prefixes used to name shapes?
Prefices are used to indicate the number of sides, angles, faces or solid angles (in 3d objects).
What shapes of diagonals cross at right angles?
The diagonals of a square and a rhombus cross at right angles.
Shapes with angles smaller than a right angle?
Acute angles
Which two shapes (A-F) have no right angles?

Properties of 3d shapes?
3D shapes have edges, sides, and intersecting points
Which shapes above hashave angles that are right angles?

How many right angles does a tetrahedron have?
a tetrahedron has 3 Right angles
How are 2d shapes similar to 3d shapes?
2D shapes and 3D shapes are similar in that they both represent geometric forms, but they differ in dimensions. While 2D shapes have only length and width, such as squares and circles, 3D shapes include depth in addition to length and width, like cubes and spheres. Both types of shapes can be defined by their properties, such as angles and sides for 2D shapes and faces and vertices for 3D shapes. Additionally, 3D shapes can be visualized as the three-dimensional counterparts of their 2D base shapes.
What are examples of 3D shape?
Some examples of 3D shapes with angles include cubes, pyramids, and rectangular prisms.
Shapes with no right angles?
Most shapes have no right angles. Circle, pentagon, hexagon etc. Ones that do include the square and some triangles.
How are prefixes used to name shapes?
Prefices are used to indicate the number of sides, angles, faces or solid angles (in 3d objects).
Which shapes angles are all right angles?
A square shape for example has 4 right angles and a right angle is 90 degrees.
What shapes have acute and right angles?
Triangles
What shapes of diagonals cross at right angles?
The diagonals of a square and a rhombus cross at right angles.
Which shapes have right angles?
right triangle square rectangle
What shapes don't have a right angles?
Shapes that do not have right angles include circles, ovals, and various types of polygons such as triangles (specifically acute and obtuse triangles), and irregular polygons. Additionally, shapes like ellipses and curves, such as parabolas, also lack right angles. These shapes can have angles of varying degrees, but none equal to 90 degrees.
What is the shapes of a cube?
A cube is a 3D solid figure whose length, width and depth are of equal measurement.
