A shape with a square base and four triangular sides is a pyramid.
There is no specific name because there is no specific shape. The shape could have anything from 5 to 13 sides depending on the sizes and orientations of the triangle and square.
It is either a square or an equilateral triangle.
A square pyramid's base is a square. You can tell by the name (for exp. a triangular pyramid's base is a triangle.) Good luck with whatever you need it for :)
A square based pyramid perhaps.
The simplest such shape is PYRAMID.
For a right angle triangle the square looking shape in the corner represents 90 degrees

yes and triangle trapezoid and rectangle

sphere
A triangular prism is so called because the shape of the ends is a triangle. A triangular pyramid is so called because the shape of the base is a triangle.
Triangle, Circle, Square, Rectangle
A square based pyramid perhaps.
A regular shape. ( square -regular rectange-, regular pentagon, regular hexagon, equilateral triangle etc. etc.)
The simplest such shape is PYRAMID.
A triangle with a rectangular base is typically referred to as a triangular prism when considering the three-dimensional shape. However, if you're referring specifically to a two-dimensional triangle that has one of its sides as the base of a rectangle, it doesn't have a unique name and is generally just called a triangle. In the context of geometry, the key characteristics would be the right angle formed at the base if the triangle is right-angled.
