What else can I help you with?
What has two pairs of parallel sides may have two acute angles of the same and two obtuse angles of the same?
The shape you are describing is a trapezoid. A trapezoid has two pairs of parallel sides, with one pair longer than the other. It can have two acute angles and two obtuse angles, depending on the lengths of the sides. The acute angles are typically smaller than 90 degrees, while the obtuse angles are larger than 90 degrees.
What number has 5 factor pairs is less than 100 and more than 50?
80 has 5 factor pairs.
Why can't a quadrilateral have no more than three obtuse angles?
The sum of all the interior angles of a quadrilateral is 360 degrees. If it had more than three obtuse angles, then it would have all four angles greater than 90 degrees so that their sum would be greater than 360 degrees.
An angle 10 more than its supplement.find the angle?
95 degrees.Supplementary angles are pairs of angles that add up to 180 degrees. So if we know that one is 10 degrees more than the other we can say that:Where x is equal to the supplement then,x + x + 10 = 180Therefore2x + 10 = 1802x = 180 - 102x = 170x = 85So the angle is 85 + 10 = 95 degrees (and its supplement is 85 degrees).
How many pairs of shoes are bought every year?
U.S. consumers purchase more than 1.3 billion pairs of shoes a year
Why do lone pairs reduce bond angles?
Lone pairs reduce bond angles because they occupy more space than bonding pairs of electrons. This increased repulsion from the lone pairs pushes the bonding pairs closer together, resulting in smaller bond angles. Additionally, lone pairs are not involved in bonding interactions, so they exert a stronger repulsive force on adjacent bonding pairs, further distorting the geometry of the molecule.
2 angles less than right angles 2 angles greater than right angles 2 pairs of parallel sides 2 pairs of equal sides?
Alright, honey, you've got yourself a trapezoid. It's got two acute angles and two obtuse angles, two pairs of parallel sides, and two pairs of equal sides. It's like the Beyoncé of quadrilaterals - fierce and fabulous.
In a linear pair of angles does one of the angles have to be obtuse?
Ordinarily, yes: one is acute (less than 90 degrees) and one is obtuse (more than 90 degrees), such that their sum is 180 degrees. The exception is if both angles are right angles (2 x 90 degrees).
Why H2S isn't a linear molecule?
because O has 2 non-bonding electron pairs. To add to this, when there are 2 non-bonding pairs, they become lone pairs which repulse the 2 hydrogen somewhat which changes the angle from 180 to 104.5.
Which would have the largest effect on a neighboring bond angle?
The largest effect on a neighboring bond angle is typically exerted by lone pairs of electrons. Lone pairs occupy more space than bonding pairs, causing the bonds around them to compress and alter the angles between neighboring bonds. Additionally, the presence of electronegative atoms can also influence bond angles by exerting inductive effects, but the impact of lone pairs is generally more significant in distorting bond angles.
Why lone pair occupy more space than bond pair?
Lone pairs occupy more space than bond pairs because they are localized on a single atom and do not have to share their electron density with another atom. This results in a greater repulsive effect on surrounding electron pairs, leading to a more expanded spatial arrangement. Additionally, lone pairs are typically larger and more diffuse than bonding pairs, which are concentrated between two nuclei. As a result, the presence of lone pairs can alter molecular geometry and bond angles.
How does a lone pair disort the moleculer shape?
A lone pair of electrons occupies space around a central atom, which can repel the bonding pairs of electrons more strongly than bonding pairs repel each other. This repulsion alters the bond angles and can lead to a distortion in the molecular shape, resulting in geometries that differ from idealized forms. For example, in water (H₂O), the two lone pairs on oxygen push the hydrogen atoms closer together, creating a bent shape rather than a linear arrangement.
How can a linear pair have one acute angle and one obtuse angle?
The two angles of a linear pair must add to 180 degrees. So if one is less than 90 degrees (acute) the other must be more than 90 degrees (obtuse).
Can a linear pair be more or less than 180 degrees?
No. They can only be exactly 180 degrees. By definition, a linear pair is a pair of two adjacent supplementary angles, so together they must form exactly 180 degrees.
Does a triangle have more angles than a pentagon?
No a pentagon has way more angles than a triangle does.
What is an angle of less than 45 degrees?
Angles less than 90 = actute Angles of 90 = right angle Angles more than 90 = obtuse Angles more than 180 = reflex
What shape has 2 pairs of equal sides but no right angles?
A parallelogram that isn't a rhombus, rectangle, or square has. Any polygon with more than 4 sides could also have.
