Does a parallelogram always have four sides?
Yes, and its opposite sides are always equal and its opposite angles are always equal. The angles and the sides can be any size.
Are trapezoids retangles?
No, trapezoids are not rectangles. While both shapes have four sides, rectangles have opposite sides that are equal in length and all interior angles are right angles, whereas trapezoids have only one pair of opposite sides that are parallel.
Do trapezoids have equal sides and angles?
Isosceles trapezoids have 2 (occasionally 3) equal sides and have 2 pairs of equal angles, but that's not case if they're not isosceles.
Does a rhombus always have 4 equal sides and angles?
It always has 4 equal sides but not 4 equal angles because it has 2 equal opposite acute angles and 2 equal opposite obtuse angles. The 4 interior angles add up to 360 degrees
How are trapezoids and squares different?
Trapezoids and squares differ in several ways. Firstly, a square has four equal sides and four 90-degree angles, while a trapezoid has only one pair of parallel sides and two non-parallel sides. Additionally, the opposite sides of a square are parallel, while in a trapezoid, only one pair of sides is parallel. Lastly, all angles in a square are equal, whereas angles in a trapezoid can be different.
Are parallelograms and trapezoids always similar?
yes * * * * * Never. A parallelogram has two pairs of equal angles opposite one another. A trapezoid does not.
Opposite angles of all parallelograms are always?
opposite angles of all parallelograms are always equal.

Yes, and its opposite sides are always equal and its opposite angles are always equal. The angles and the sides can be any size.

If a quadrilateral is a parallelogram then its opposite angles are always supplementary?
False because it will have 2 equal opposite obtuse angles and 2 equal opposite acute angles with the 4 angles adding up to 360 degrees.
If a quadrilateral is a parallelogram will it always have equal angles?
Diagonally opposite pairs of angles will always be equal, but the only time all angles in a quadrilateral parallelogram are equal is when that shape is a rectangle.
Are opposite angles always equal in isosceles trapezoid?
They are, yes.
What are allied angles?
Allied (or co-interior) angles are supplementary. Vertically opposite angles are always equal.
Are the interior angles of a parallelogram always congruent?
Only if it is a rectangle otherwise it has equal opposite acute angles and equal opposite obtuse angles and the 4 interior angles add up to 360 degrees
