Yes its base contains 4 corner right angles
Shadow of a building have right angles at the base of the building. Braces of buildings have right angles.
Sum of exterior angles: 360 degrees Sum of interior angles: 180 degrees The square of its hypotenuse is equal to the sum of its base squared plus its height squared.
A lot of things. For example, a cube has 8 vertices, the square pyramid has 5. A cube also has more edges and faces than the pyramid. All the faces of the cube are squares, while the pyramid only has one square face. Also, all the angles in the cube are right angles, while the angles in a square pyramid (in the usual sense of a pyramid where the apex is directly above the center of the base) are acute. In any case, they are not all right angles.

no... they do not have right angles connected to the sides
Yes - it has four around the base !
It all depends on what the base is. Th number of faces a pyrimad has is the number sides on the base+1. So for example, a square pyrimad (one of the most common) would have 4 +1 or 5 sides.
Yes its base contains 4 corner right angles
A square pyramid has a total of 8 angles. Each of the 4 triangular faces has 3 angles, totaling 12 angles. However, 4 of these angles are shared where the faces meet at the base, resulting in a total of 8 unique angles in a square pyramid.
Just the one and it is the base face
More correctly it is a 'Tetrahedron'. A Tetrahedron is a solid object with '4' (four) triangular faces. The Pyramids of Egypt are NOT tetrahedrons, because they have five(5) faces. made up of 4 triangular faces ( which you see) , and a SQUARE BAse (5th face) which they are built on.
At least 4 - on the four corners of the base. But there could be two more if the opposite pairs of sloping edges met at the apex at right angles.
Since the base and height for a square are always equal, and all angles included are right angles (90 degrees), it is common to refer to each as a side. All sides are of equal length, and base = height.
It depends on the prism. A prism that has a regular pentagon as base but is not a right prism has no right angles. At the other extreme, consider a right prism whose bases are pentagons that resemble a child's drawing of a house (square with a triangle roof). If the angles of the roof triangle are 90-45-45, the prism will have 22 right angles.
