square
the sine rule, angle (a) and opposite length is eaqual to angle (b) and opposite length. which are also equal to angle (c) and opposite length. Sin A = Sin B = Sin C ------- -------- ---------- a -------- b -------- c
This is a rectangle, or the special case of the square (all sides equal).
A quadrilateral where each angle is a right angle is called a rectangle. In addition to having four right angles, a rectangle also has opposite sides that are equal in length. If all four sides are of equal length, it is specifically termed a square. Thus, all rectangles are quadrilaterals, but not all quadrilaterals with right angles are rectangles unless they also have equal opposite sides.
Opposite angles are equal
A parallelogram is a quadrilateral with 2 pairs of parallel sides and a rhombus is a 4 sided figure (thus a quadrilateral) with all sides of equal length. Because opposite sides are of equal length opposite angles must also be equal. This angle measure defines a parallelogram.
A Rhombus
a pentagon
the tangent of an angle is equal to the length of the opposite side from the angle divided by the length of the side adjacent to the angle.

True. In any triangle, the longest side is always opposite the largest angle; the shortest side is always opposite the shortest angle; and the middle length side is always opposite the middle size angle. In an isosceles triangle, there is no middle length side; and the two sides of equal length are opposite the angles of equal size. In an equilateral triangle, all sides are the same length, as are all the angles.

its a rhombus
If all pairs of opposite sides are parallel, each pair must be equal.

It has 2 pairs of equal opposite parallel sides

are the opposite angle of parallelogram equal
