# What are the interior angles of a parallelogram when two of its angles are 2x and x degrees?

They work out as two equal opposite angles of 120 degrees and two equal opposite angles of 60 degrees.

### Can a parallelogram measure 45 angles and two 75 angles why or why not?

No because the total sum of interior angles of a parallelogram are 360 degrees.

### What are the angles of a parallelogram when two of its interior angles are 2x degrees and x degrees?

If: 2x+2x+x+x = 360 degrees then x = 60 degrees. Therefore angles are: 60 degrees, 60 degrees, 120 degrees and 120 degrees

### Can a parallelogram have two 45 degree angles and another angle two 75 degree angles?

No because the 4 interior angles must add up to 360 degrees

### What characteristics help you classifly a quadrilateral as a parallelogram and not a rectangle?

A rectangle has four interior angles that are exactly 90 degrees. A parallelogram can have two opposite angles larger than 90 and the other two, smaller than 90 degrees but still add up to 360 degrees.

### What is a parallelogram with one interior angle equal to 90?

It is a square, a regular parallelogram with all right angles. The reason is that in a parallelogram, the adjacent angles are supplementary (equal 180 degrees). In any case, the opposite angle would be 90 degrees as well, leaving just 180 degrees for the other two identical opposite angles.

### What could describe a quadrilateral with two pairs of parallel sides and two interior angles that measure 65 degrees?

A rhombus or a parallelogram

### What type of quadrilateral has two 80 degree angles and two 100 degree angles and why?

It could be a parallelogram because opposite angles are equal and its 4 interior angles add up to 360 degrees

### Can a paralleogram have two 45 angles and two 75 angles why or why not?

No it cannot, because the interior angles of a parallelogram ... or of any four-sided figure for that matter ... must add up to 360 degrees.

### What is the measure of a interior angle of a parallelogram?

You cant tell. There are an infinite number of parallelograms. The only thing you know is that all four interior angles add up to 360 degrees. Also, I guess, any two adjacent interior angles add up to 180 degrees.

### What make a parallelogram and a trapezoid alike?

Each of them has four sides. Each of them has four angles. Each of them has interior angles that sum to 360 degrees. Each of them has exterior angles that sum to 360 degrees. Each of them has two diagonals. Each of them has at least two sides that are parallel.

### 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… Read More

### Does a parallelogram have two pairs of equal angles?

Yes and they are one pair of opposite equal acute angles and one pair of opposite equal obtuse angles. Its 4 interior angles add up to 360 degrees.

### How are a rectangle and a parallelogram different?

The main difference is that a rectangle has 4 equal interior right angles whereas a parallelogram has 2 equal interior obtuse angles and 2 equal interior acute angles Both have two sets of parallel lines, but a rectangle forms four equal 90 degree angles. A parallelogram does not have four equal 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.

### Can a parallelogram have two 45 degree angles and two 75 degree angles?

No - the 4 internal angles of a parallelogram will always add up to 360 degrees.

### 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 =… Read More

### One angle of a parallelogram measures 10 degrees. What are the measures of the other three angles in the parallelogram?

If one angle is 10 degrees, its opposite angle is also 10 degrees. Since consecutive angles are supplementary, each pair of angles has to add up to 180 degrees so the other angles have to be 170 degrees. Therefore this parallelogram has two 10 degree angles and two 170 degree angles.

### Why is a parallelogram not a square?

Two reasons: 1) The interior angles of a parallelogram aren't necessarily 90 degrees. 2) All fours side are not necessarily equal in a parallelogram (we are only guaranteed two pairs of equal sides. Note that all squares are parallelograms, though.

### If two angles in a parallelogram are equal to 35 degrees what are the measurements of the other two angles?

The sum of the internal angles in a parallelogram is 360 degrees. Since there are two equal pairs of angles measuring the same, then each of the second pair of angles is equal to (360 - (35 x 2)) / 2 = 145 degrees.

### How many obtuse angles has a parallelogram got?

### The sum of interior angles of a square is?

360 degrees. Same for any other rectangle, rhombus, parallelogram, or convex quadrilateral. The reason is that any quadrilateral can be divided into two triangles by drawing a diagonal and the sum of the angles of each triangle is 180 degrees.

### What is the same between a parallelgram and a rhombus?

They both have four sides, four interior angles that total 360 degrees, and two pairs of equal, parallel opposite sides. Every rhombus is a parallelogram, but not every parallelogram is a rhombus.

### Can a parallelogram have two 45 angles and two 75 angles?

No, because it doesn't equal 360 degrees

### Can a parallelogram have two 45 degres angles and two 75 degrees why or why not?

### How many degrees does a parallelogram have to add up to?

360 degrees. This complies with the rules of parallelograms. A parallelogram is a quadrilateral comprised of two sets of parallel lines. The opposite sides of a parallelogram are congruent, meaning that they have the same shape and size. The opposite angles are also congruent. Additionally, its consecutive angles are supplementary. This means that when when you add the two angles next to each other together, they will add up to 180 degrees, or a straight… Read More

### What angles do a scalene triangle have?

### How Dow you that the opposite angles of a parallelogram are equal?

First of all, you know the opposite sides of a parallelogram are equal because of the definition of a parallelogram. Therefore, two adjacent angles in the parallelogram are supplementary, because same-side interior angles in two parallels and a transversal are always supplementary. Therefore, opposite angles in a paralellogram are equal, because two angles both supplementary to a third angle are equal to each other.

### What are the angles in a parallelogram if the measure of one interior angle is 50 degrees more than 4 times the measure of another angle?

Opposite angles of a parallelogram are equal, and adjacent angles are supplementary. Let one angle be Î¸, then the adjacent angle is 4Î¸ + 50Â° â†’ Î¸ + 4Î¸ + 50Â° = 180Â° â†’ 5Î¸ = 130Â° â†’ Î¸ = 26Â° â†’ The two adjacent angles are 26Â° and 154Â°. â†’ The angles of the parallelogram are 26Â°, 154Â°, 26Â°, 154Â°.

All angles of a parallelogram add up to 360 and opposite angles are always equal. Therefore 360 - 80 = 280 The other angles = 140 each Test 40 + 40 + 140 + 140 = 360

### Why does a triangle have two acute angles?

If there were less than two acute angles, there would be two (or more angles that were 90 degrees or more. Then the sum of the three angles of the triangle would be more than 180 degrees. But this is not possible because the interior angles of a triangle sum to 180 degrees.

### Is it true that measures of two adjacent interior angles sum to 180 because they form a linear pair?

only in a parallelogram
