Throughout history, technological developments have enabled artists and architects to express ideas in new ways. choose and fully identify two works of art or architecture and the specific technological development that made each work possible. one of your choices must date before 1800 and one must date after 1800. for each work, analyze how the technological development enabled the artist or architect to express ideas in new ways.

How is this even a question?

In a right-angled triangle: 1- the hypotenuse is the longest side2- we can apply pythagorean rule which states that: (hypotenuse)^2 = (side1)^2 + (side2)^2for the given triangle,longest side is 15 cm  side1 = 9 cmside2 is 12 cm  to check whether the triangle is right-angled or not,compare (15)^2 to the summation of (9)^2 and (12)^in other words, compare 225 to the summation of 81 and 144if they are both equal, then the triangle is right-angles, otherwise, it is not.you haven't provided the diagram showing her work, so i cannot tell the choice. however, apply my explanation to the question you have.
