If two of the angles of a parallelogram are acute, then the other two angles will be obtuse. Since a parallelogram contains two pairs of parallel sides, both of the acute angles and both of the obtuse angles respectively will measure the same.

What is the other angle of a parallelogram with an acute angle 35 degrees?
The other angles are 145°, 35°, and 145°.
Is angle in a parallelogram vertical to each other?
The term parallelogram refers to a four sided geometrical figure (in other words, a quadrilateral) in which there are two sets of parallel sides. The angles can vary; they can be right angles, or they can be acute or obtuse angles, as long as there are two sets of parallel sides. Angles are not said to be vertical to each other. Angles can be perpendicular to each other, but not vertical or horizontal. If angles are perpendicular, then they are right angles, in other words, 90o angles. Lines can be vertical, but angles can't.
Which parallelogram has two pairs of parallel sides and no right angles?
A rhombus has two opposing acute angles (less than 90º) and two opposing obtuse (greater than 90º) angles, with the opposing sides being parallel and the sides being of equal length. A parallelogram can have the two acute angles and two obtuse angles, but have sides of different lengths. That is: two opposing sides shorter than the other two opposing sides. All angles total 360º
Are opposite angles of a parallelogram congruent for all parallelograms?
angles diagnal from each other in a parallelogram are congruent for shape be parallelogram, all sides must be parallel
If two angles of a triangle are acute must the the third angle always be acute?
No. In fact, if one of the angles is not acute (a right angle or obtuse), the other two must be acute.
What is the other angle of a parallelogram with an acute angle 35 degrees?
The other angles are 145°, 35°, and 145°.
Which 2-D shapes can have 2 acute angles and 2 obtuse angles?
With 2 acute and 2 obtuse angles it has 4 angles - the shape is a quadrilateral. The shape can be one of trapezium, parallelogram, rhombus, kite or a general quadrilateral. With the two acute angles next to each other (forcing the two obtuse angles to be next to each other) the shape can be either a trapezium or a general quadrilateral.

Is it possible that all sides are equal but all angles are not ina parallelogram?
Yes. In a non-trivial rhombus (ie one that is not a square), a pair of opposite angles is acute and the other pair is obtuse.
Which parallelogram has two pairs of parallel sides and no right angles?
A rhombus has two opposing acute angles (less than 90º) and two opposing obtuse (greater than 90º) angles, with the opposing sides being parallel and the sides being of equal length. A parallelogram can have the two acute angles and two obtuse angles, but have sides of different lengths. That is: two opposing sides shorter than the other two opposing sides. All angles total 360º
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
Are complementary angles consecutive angles in a parallelogram?
The question does not really make sense. Once might ask, "Are consecutive angles in a parallelogram complementary?" in which case the answer is no. Complementary angles are angles which add up to 90 degrees. Consecutive angles are angles next to each other (or follow each other). In a parallelogram, consecutive angles are supplementary (add to 180 degrees). In a parallelogram, opposite angles are equal. You could have a parallelogram where two angles are 45 degree (and thus complementary) and then the other two angles would be 135 degrees.
If two angles of a triangle are acute then the third must be?
Actually, you cannot conclude anything this way, at least not in regular geometry. For instance, in a "perfect triangle," all 3 angles are acute. In a right triangle, one is a right angle and the other two are acute. It is also possible to have an obtuse angle and two acute angles. The thing is, the 3 angles must add up to 180 degrees.
The acute angles of a right triangle are?
In a right angled triangle the two other angles are acute.
What are the acute angles of a right triangle?
In a right angled triangle the two other angles are acute.
Are opposite angles of a parallelogram congruent for all parallelograms?
angles diagnal from each other in a parallelogram are congruent for shape be parallelogram, all sides must be parallel
Does a parallelogram have obtuse angles?
can do depends on what parallelogram it is. A parallelogram is a 4 sided shape with opposite sides equal in length and parallel, and opposite angles equal. So if two of the angles are acute (less than 90o), their sum is less than 180o, leaving greater than 180o for the remaining two angles (since the four angles sum to 360o as the shape is a quadrilateral), meaning that each of them is greater than 90o and thus obtuse. However, if two of the angles are 90o, then the other two are also 90o and so all the angles are right angles and none of them is obtuse. (A rectangle is a parallelogram as it has opposite sides of equal length and parallel, and opposite angles equal.)
