How many angles does the icosahedron have?
A regular icosahedron has 20 faces (equilateral triangles), 30 edges and 12 vertices.
How do crystal systems differ?
In the angles between faces and the number of edges of equal length

A pyramid has five faces, and two of those faces are triangles.
How many faces of a rectangular pyramid are triangles?
4 of the faces of a Rectangular Pyramide are triangles.
Why are pyramids isosceles triangles?
Pyramids are not isosceles triangles but their triangular faces can form the image of an isosceles triangle if they have two sides of equal lengths and a base of a different length.

How many 90 degree angles does a triangular prism have?
A triangular prism has three rectangular faces which, between them, will have 4*3 = 12 right angles. It also has two triangular faces and these can have another 2 right angles. So the answer is 12 or 14, depending on whether the triangles are right angled or not.
What do the regular tetrahedron octahedron and icosahedron have in common?
Their faces are equilateral triangles.
Are the side faces of a pyramid triangles?
yes they are triangles
Is the tetrahedron a regular polyhedron?
Not necessarily. If all faces are equilateral triangles (all edges are equal length) then it is a regular polyhedron.
How many angles triangles circles and rectangles are in a rectangular prism?
In a rectangular prism, there are 8 corners, or vertices. each corner has 3 dimensions, so there would be 3 angles per corner, for a grand total of 24 angles. There are no triangular or circular faces on a rectangular prism. There are 6 rectangular faces.
