A rectangular-based pyramid.
Apart from both being a geometric 2D shape, there is little similarity between the two. A rectangle has four parallel sides and a right-angle in each of the four corners. A right-angle triangle has three sides and only a right-angle in one corner.
A rectangle has 4 interior angles each being right angles
All triangles inscribed in a semicircle with one side of the triangle being the diameter of the semicircle are right triangles.
MULTIPLICATION area for a rectangle is A = L * W * H where, A = area of rectangle L = Length of rectangle W = width of rectangle H = height of rectangle The dimensions of a rectangle (L, W, and H) are interchangeable because they are being multiplied together and hence each side of the rectangle can be arbitrarily assigned to a dimension.
A pyramid. The square being the base and the triangles the 'sides' - each having a side connected to a side of the square - the other sides connected to 'neighbor-triangles'.
Because otherwise you would have found the area of the rectangle/square (the rectangle/square being if you put two of the triangles together).
Area = Length x width It's the same as the area for a rectangle - base times height. If you think about it, a parallelogram is a rectangle with two triangles on either side - one with its base on top, one with its base on bottom. Through various identities, we know that these two triangles are congruent. So the area is the sum of the small rectangle plus the two triangles, which ends up being base times height.
Yes. You can even have two triangles with two pairs of sides that are the SAME measure without the triangles being similar.

Any rectangle will do as an example.
No. Only right triangles do, and not all triangles can be right triangles. Equilateral triangles, for example, are always 60°-60°-60°. Isosceles and scalene triangles can be right triangles; all isosceles triangles have the additional useful property of being able to be split into two right triangles.
AA
A square is a rectangle with every side being congruent to every other side.

False. Equilateral triangles are equilateral. All isosceles triangles have two of the sides the same, with the hypotenuse being longer than the other two.
