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;
Similar to alternate interior angles, alternate exterior angles are also congruent to each other if (and only if) the two lines intersected by the transversal are parallel. These angles are on opposite sides of the transversal, but outside the two lines the transversal intersects.
