The sun is approximately 400 times the size of the moon, however, it is also approximately 400 times farther away. This relationship cancels out and makes the sun and the moon appear observationally to be the same size on earth.
They appear to be the same size, as the sun is a very long distance away. The sun is many times larger than the moon.
Under what circumstance is this visible?
The sun and the moon are the same distance from the earth
Maybe it appears to be of same size to naked eyes, but actually Moon's orbit around Earth is not perfectly round but is oval or elliptical in shape. As the Moon orbits our planet, it's distance varies from about 221,000 to 252,000 miles. This 13% variation in the Moon's distance makes the Moon's apparent size in our sky vary by the same amount
Because the shape and size of the object dont change, only the gravity affecting it

Even tho the Moon is much smaller than the Sun, they appear to be the same size in the say, because the Moon is so much closer to the earth.
You would need to be in a very special spot ... or so far away that both of them appeared to simply be points of light ... in order for the Moon to appear to be the same size as the Earth.Perhaps you meant "why does the Moon appear to be the same size as the Sun" (when seen from Earth), and the answer is ... there isn't any deep reason why this should be the case, it just happens to be true. Strictly speaking it's only true now: in the distant past the Moon appeared larger than the Sun, and in the distant future the Moon will appear smaller than the Sun. By happenstance we (and by "we" I really mean "human civilization", because this is not changing very fast at all) happen to be living in the time when the Moon and the Sun appear to be roughly the same size.
Because of the Earths rotation, Happy astronomy! :)
The word "congruent" means the same shape and same size.
it is similar, easy as that. congruent is same shape same size ans similar is same shape different size similar=two figures that have the same shape, but not necessarily the same size
Having the same size and shape means that you look the same height and size.
Congruent Polygons are the same shape and size.
The moon is always the same size it may appear bigger because more of the sun's light is shining on it, but no the moon does not "grow" or "shrink".
Similar means that the figures are the same shape yet not the same size. If the figures are the exact same size and shape, then they are congruent.
