From September 21 until March 21, the shortest shadow points north from the equator. From March 21 until September 21, the shortest shadow points south from the equator.
Well, no trees have a shadow if it is dark, or if they are shaded by a bigger tree. But a family tree may have no shadow.
Light travels in straight lines and therefore some will hit the tree. Where this happens a shadow (absence of light) is created behind the tree.
Let the height of the tree be x: x/10 = 5/4 x = 50/4 The tree is 12.5 feet
4.5 ft
The shadow of the tree would be shortest at midday when the sun is directly overhead. This is because the angle of the sunlight is most perpendicular to the tree, resulting in a shorter shadow. At sunrise and sunset, the angle of the sunlight is lower, creating longer shadows.
noon
noon
The shortest shadow on a sundial would be afternoon or Middaay
The shortest shadow is at noon because the sun is directly above you
The man is twice as high as his shadow. Therefore, the tree must also be twice as high as its shadow, which would make the tree 40 feet tall.

The shortest shadow occurs at noon.
June 21, because the Sun is highest in the sky
A tree's shadow does not have light. Anytime you are in the shadow of another object your body has no shadow of its own.
At noon, or when the sun is in the middle of the sun is in the middle of the sky. It is directly above you so it casts arely any shadow. One could argue that it is shortest at night, when it is non-existent, but that technically means that there is no shadow to measure.
