Neptune: With temperatures dropping to -218Â°C in Neptuneâs upper atmosphere, the planet is one of the coldest in our Solar System. And like all of the gas giants, Neptune has a much hotter core, which is around 7,000Â°C.ercury: Of our eight planets, Mercury is closest to the Sun. As such, one would expect it to experience the hottest temperatures in our Solar System. However, since Mercury also has no atmosphere and it also spins very slowly compared to the other planets, the surface temperature varies quite widely.
A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. On the other hand, not all quadrilaterals and parallelograms are rectangles. A rectangle has all the properties of a parallelogram, plus the following: 1  The diagonals are congruent. parallelogram is a quadrilateral in which both pairs of opposite sides are parallel. A parallelogram also has the following properties: 1  Opposite angles are congruent; 2  Opposite sides are congruent; 3  Adjacent angles are supplementary;
Exterior angles add up to 360 degrees. Opposite sides are congruent. Opposite sides are parallel. Opposite angles are congruent. Adjacent angles are supplementary. Diagonal midpoints make perpendicular lines. A square satisfies all of those requirements. A squre is a parallelogram, a quadrilateral, and a rhombus.
