Does a parallelogram have parellel and perpendicular lines?
Yes, if it is an equiangular or equiangular and equilateral parallelogram (rectangle or square).
Is a parallelogram always equiangular?
No. A parallelogram has two pairs of opposite angles that are equal but to be equiangular, all four angles must be the same. That is not necessarily the case in a parallelogram.
What is an equiangular parallelogram?
square or rhombus
Are all rombi squares?
A rhombus cannot be a square. A rectangle is an equiangular parallelogram. A rhombus is an equilateral parallelogram. A square is an equilateral and equiangular parallelogram. Thus, a square is both a rectangle and a rhombus.
Why is a square called a rectangle?
A rectangle is defined as: A quadrilateral with two sets of congruent sides. Therefore, a square is a TYPE of rectangle. Rectangles and squares belong to the set of parallelograms, so they have all properties of a parallelogram. A rectangle is an equiangular parallelogram, while a square is an equilateral and equiangular parallelogram. Thus, a square is a rectangle.

A parallelogram which is equilatral is a?
that is a square, which would also be equiangular
What does a equiangular look like?
A parallelogram with equal angles. And when a parallelogram has equal angles, it has equal sides as well.
Which of these shapes is always equiangular a rectangle a rhombus a trapezoid a parallelogram?
a rectangle

Is a parallelogram and rhombus equiangular?
There is not enough information to answer this question. A rhombus is a special case of parallelograms where all the sides are the same length. This says nothing about the angles of the parallelogram and the rhombus. ■
Can a shape be a square and a parrallelogram and rhombus?
Yes, but only if it is a square. A square is an equiangular rhombus, and a rhombus is an equilateral parallelogram.
What is the math definition for a rectangle?
In Euclidean plane geometry, a rectangle is any quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°). It can also be defined as a parallelogram containing a right angle.
What shape has all opposite sides but no perpendicular sides?
Any non-equiangular parallelogram, and any regular polygonwith an even number of sides more than 4.
