What else can I help you with?
Opposite angles of all parallelograms are always?
opposite angles of all parallelograms are always equal.
If two parallelograms are similar then the corresponding angles are what?
If two parallelograms are similar then the corresponding angles are EQUAL.
What describes the angles of some parallelograms?
In all parallelograms, opposite angles are equal and the 4 interior angles add up to 360 degrees. In someparallelograms, all of the angles are 90 degrees. These parallelograms are rectangles.
Are all parallelograms a rectangle?
No, because to have a rectangle, you need to have four right angles, and parallelograms dont have to have right angles. However, all rectangles are parallelograms.
What is true of rectangles that isn't true of parallelograms in general?
All rectangles have 90 degree angles and with parallelograms that does not always have to be the case. But no matter what in order for a parallelogram to be a rectangle the angles have to all be 90 degrees.Rectangles are special cases of parallelograms. They have all the properties of parallelograms, and in addition, all their internal angles are right-angles - 90° angles.
All rectangles are parallelograms. are all parallelograms rectangles explain.?
All parallelograms are not rectangles. The angles of a parallelogram need not be right angles and so the figure need not be a rectangle.
Why are parallelograms not rectangles?
Parallelograms do not have right angles. A rectangle is a parallelogram but a parallelogram is not a rectangle.
Are rectangles are parallelograms?
Parallelograms do not have right angles. A rectangle is a parallelogram but a parallelogram is not a rectangle.
Do parallelograms have no congruent angles?
Parallelograms normally have 2 congruent obtuse angles and 2 congruent acute angles that altogether add up to 360 degrees
What kind of angles do parallelograms have?
Acute, obtuse and opposite angles are equal
When are parallelograms rectangles?
When the corner angles are right-angles (90 degrees)
Do all parallelograms have 4 equal angles?
No
