## How many obtuse angles are in parallelogram?

two obtuse angles

Thus, at any given time, a parallelogram has two obtuse angles that are equal and the other two angles are acute and they are also equal. All angles measuring more than 90° and less than 180° are called obtuse angles.

**How many acute angles are in a parallelogram?**

2 acute

In a parallelogram, adjacent angles sum to 180°. Thus, there’re 2 acute and 2 obtuse angles in a parallelogram. Hence, 2 acute angles a parallelogram has.

### What parallelogram is not a rectangle?

The answer is yes! The two pairs of opposite angles of a rhombus are always equal, just like the two pairs of opposite angles of a parallelogram are always equal. This means that a rhombus is just a special case of a parallelogram where all four sides happen to also be congruent.

**Does a parallelogram always have an obtuse angle?**

No, a parallelogram cannot have 4 obtuse angles. An obtuse angle is an angle with a measure that is greater than 90°.

## Are all angles in a parallelogram congruent?

Basic Properties of Parallelograms Inside a parallelogram, opposite angles are always congruent. Angles that lie next to each other are always supplementary (add up to 180 degrees).

**Does a parallelogram have four right angles?**

Special Quadrilaterals A parallelogram has two parallel pairs of opposite sides. A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides. A square has two pairs of parallel sides, four right angles, and all four sides are equal.

### Is parallelogram a rectangle yes or no?

This is always true. Â Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Parallelograms are quadrilaterals with two sets of parallel sides. A parallelogram is a rectangle.

**Which angles in a parallelogram are congruent?**

Parallelogram: A quadrilateral with two pairs of parallel lines. To start off with basic rules, opposite sides of a parallelogram are always equal length and parallel. Inside a parallelogram, opposite angles are always congruent. Angles that lie next to each other are always supplementary (add up to 180 degrees).

## What parallelogram has consecutive angles are congruent?

A rectangle is a parallelogram, so its opposite angles are congruent and its consecutive angles are supplementary. Recall that the supplement of a right angle is another right angle. So a rectangle actually has four right angles.

**Can a parallelogram have right angles yes or no?**

Right Angles in Parallelograms In a parallelogram, if one of the angles is a right angle, all four angles must be right angles. If a four-sided figure has one right angle and at least one angle of a different measure, it is not a parallelogram; it is a trapezoid.

### What is a parallelogram with no right angles?

This parallelogram is a rhomboid as it has no right angles and unequal sides. …
