Which pyramid is the highest-sloped among the Giza pyramids?

Explanation:
What the question tests is how to compare the steepness of pyramid faces. The slope of a pyramid’s sides depends on how tall it is relative to how wide its base is. For a square-based pyramid, you can think of the face angle as determined by the ratio of height to half the base: a larger ratio means a steeper face. Looking at the Giza pyramids, the Pyramid of Khafre has a steeper face than the Pyramid of Khufu and than Menkaure. Khafre’s base is about 215 meters square and its original height around 143 meters, giving a face angle in the low 50s to around 53 degrees. Khufu’s Great Pyramid, while taller, sits on a slightly broader footprint, yielding a somewhat shallower face angle—roughly around 52 degrees. Menkaure is smaller, with a base just over 100 meters and a height around 65 meters, producing a noticeably gentler slope. Note that the Bent Pyramid and Red Pyramid aren’t at Giza; they’re at Dahshur and have different, generally steeper or shallower slopes, but they’re not part of the Giza set. So, among the pyramids at Giza, the steepest sides belong to the Pyramid of Khafre.
