In a parallelogram opposite angles are equal. Thus angle c = angle a = 40o.
The sum of all the angles in a quadrilateral is 360o, so:
angle a + angle b + angle c + angle d = 360o
=> 40o + angle b + 40o + angle d = 360o
=> angle b + angle d = 280o.

Abcd is a quadrilateral in which angle a equals 40 degrees and angle b equals 150 degrees could abcd be a parallelogram?
never
Quadrilateral abcd is a parallelogram in which angle a equals 40 degrees quadrilateral abcd could also be called a?
none of these answers are correct
Are all angles of a parallelogram equal to 90 degrees?
No, only in a square (regular parallelogram).The opposite angles are EQUAL in a parallelogram, and the adjacent angles are SUPPLEMENTARY(they equal 180 degrees).So if any angle in a parallelogram is a right angle, they all are. Otherwise, there are no right angles.The angles of a parallelogram will average 90 degrees, as there are 360 degrees in any quadrilateral, (360/4 - 90) and 180 degrees in two adjacent non-equal angles (180/2 = 90).
If quadrilateral ABCD is a parallelogram in which angle B equals 100 degrees how many degrees would be a plus c?
A = C = 180 - B = 80 So A + C = 160
What is a quadrilateral with two pairs of parallel and congruent sides?
A rhombus, or a square if there is a 90o angle.

never
Quadrilateral abcd is a parallelogram in which angle a equals 40 degrees quadrilateral abcd could also be called a?

Quadrilateral ABCD is a parallelogram in which angle A equals 40 degrees?
none of these are correct
Does a parallelogram have a 90 degree angle?
No , a parallelogram can not have a 90 Degree angle .Reason : A Parallelogram can be defined as a quadrilateral whose two s sides are parallel to each other and all the four angles at the vertices are not 90 degrees or right angles, then the quadrilateral is called a parallelogram.
Is each interior angle of a quadrilateral always 90 degrees?
No. in a rhombus the angles are not 90 degrees. also in a parallelogram they are not 90 degrees
Quadrilateral abcd is a parallelogram in which angle a equals 40 degrees b plus d equals degrees?
280
What measure of angle a will make this quadrilateral a parallelogram?
360
If a parallelogram has a right angle is it a rectangle?
No because it could be an irregular quadrilateral that includes a right angle. A rectangle has four right angles.Yes, a parallelogram with a right angle is always a rectangle. In fact, in my geometry book, some 55 years ago, such was the definition of rectangle.A parallelogram with one right angle will always have four right angles.It is true that you can draw an irregular quadrilateral with a right angle which is not a rectangle but the figure will not be a parallelogram.
Quadrilateral ABCD is a parallelogram If angle A measures 70 degrees what are the measures of angles B C and D?
B 110 degrees C 70 degrees D 110 degrees
Can a parallelogram always be inscribed in a circle?
No. For example, if one angle measures 100 degrees, and its adjacent angle is 80 degrees, then the opposite angles would be either 200 or 160 degrees, but in order for a quadrilateral to be inscribed in a circle the opposite angles would have to equal 180 degrees. A parallelogram can be inscribed in a circle if it is a rectangle.
What quadrilateral that does not always have a right angle?
Trapezoid, Parallelogram, Rhombus.
What quadrilateral is two pair of opposite angle congruent?
Parallelogram
