3 things unique about a rectangle?
It is a parallelogram with 4 right angles and it has congruent diagonals that bisect.
What is a shape that has two pair of equal sides and no right angles and is not a parallelogram?
Any shape with more than 3 sides can have two pairs of equal sides and no right angles. If it only has 4 sides in total and isn't a parallelogram, then it's a trapezoid.
What is the difference between a parallelogram and a triangle?
A parallelogram has 4 sides and 4 angles that add up to 360 degrees whereas a triangle has 3 sides and 3 angles that add up to 180 degrees.
How can you construct a 120 degree angle without using a protractor?
Construct an equilateral triangle which will have 3 equal interior angles of 60 degrees and 3 equal exterior angles of 120 degrees
What are the other angles of a parallelogram when one interior angle is 27.5 degrees?
The other 3 angles are 27.5 degrees, 152.5 degrees and 152.5 degrees because opposite angles are equal in a parallelogram and its 4 interior angles add up to 360 degrees.
Can a parallelogram can have at most 3 right angles?
No because a parallelogram in the shape of a rectangle has 4 right angles
Can a parallelogram have 3 right angles?
Depends on your question. A rectangle is a parallelogram and has 4 right angles. BUT A parallelogram can have only a total of one, two, or four right angles. Mathematically, 3 right angles is 270 degrees. A parallelogram has 360 degrees. 360 - 270 = 90 degrees = right angle.
How many congruent angles in a parallelogram with no right angles?
3
3 names for a polygon that has 4 equal sides and no right angles?
A rhombus, an equal sided parallelogram or an equal sided quadrilateral with no right angles.

Which polygon has no right angles and 3 congruent sides of rhombus equilateral triangle pparallelogram and trapezoid?
parallelogram
What is a shape that has two pair of equal sides and no right angles and is not a parallelogram?
Any shape with more than 3 sides can have two pairs of equal sides and no right angles. If it only has 4 sides in total and isn't a parallelogram, then it's a trapezoid.
Does a pentagon have 5 right angles or 3?
Pentagons in normal (Euclidean) geometry can have at most three right angles, and the other two will be obtuse.However, in hyperbolic geometry, it is possible to construct a pentagon with 5 right angles, which is called a rectapentagon.
How do you find missing angle of a parallelogram?
Being a quadrilateral, the sum of all four angles is 360o.Opposite angles of a parallelogram are equal.Adjacent angles of a parallelogram are supplementary, that is add to 180o.Given one angle of a parallelogram, the other 3 angles can be calculated:the opposite angle is the same;the other two angles are the same as each other and are 180o - the_given_angle
What is the difference between a parallelogram and a triangle?
A parallelogram has 4 sides and 4 angles that add up to 360 degrees whereas a triangle has 3 sides and 3 angles that add up to 180 degrees.
What are the angles of a triangle parallelogram pentagon and a hexagon?
Triangle has 3 angles adding to 180 degrees Parallelogram has 4 angles adding to 360 degrees Pentagon has 5 angles adding to 540 degrees Heaxagon has 6 angles adding to 720 degrees
How can you construct a 120 degree angle without using a protractor?
Construct an equilateral triangle which will have 3 equal interior angles of 60 degrees and 3 equal exterior angles of 120 degrees
