What is the meaning of sound energy
What is the definition of sound energy and examples?
Sound energy is defined as the movement of vibrations through matter. Sound energy is produced when an object vibrates, which results in noise. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood, or metal.
What is sound energy in basic science?
Sound is a form of energy (wave motion) which is transmitted through an elastic medium from a vibrating body to a listener. Sound may be defined as a sensation produced through the organs of hearing. Every sound is produced by a vibrating body.

Complementary angles are those that sum up to 90o . Vertical angles have equal measures. Therefore, if vertical angles measure 45o each, they are complementary.
Which angles form a vertical pair?
Vertical angles are a pair of non-adjacent angles formed by the intersection of two straight line. Vertical angles are located across from one another in the corners of the “X” formed by two straight lines. In the diagram at the right, lines m and n are straight: ∠1 and ∠2 are vertical angles.
Which of the following pairs of angles is not a pair of complementary angles?
Explanation: Complementary angle pairs’ sum is always 90° . 160° and 30° added up is 190°. So, it’s not a pair of complementary angles.

Do Linear pairs add up to 180?
The two angles of a linear pair are always supplementary , which means their measures add up to 180° .
How do you know if angles are linear pairs?
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
How can the properties of linear pairs and vertical angles help?
If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.
Can you assume a linear pair?
In this book, you can assume from a diagram that two adjacent angles form a linear pair if the noncommon sides appear to lie on the same line.
Which of the following pairs of angles from a linear pair?
A linear pair is a pair of adjacent angles formed when two lines intersect. In the figure, ∠1 and ∠2 form a linear pair. So do ∠2 and ∠3 , ∠3 and ∠4 , and ∠1 and ∠4 .
What is the angle rule for vertically opposite angles?
The angles opposite each other when two lines cross. They are always equal.
How do you prove that two angles form a linear pair?
More formally, two angles form a linear pair if and only if all of the following conditions hold:
- the two angles share a side;
- the two angles share a vertex (meaning the lines that form the two angles all meet at the same point);
- the sides that the angles do not share lie on the same line.
Are vertical angles supplementary?
Vertical angles are supplementary angles when the lines intersect perpendicularly. For example, ∠W and ∠ Y are vertical angles which are also supplementary angles.
Do linear pairs have to be adjacent?
linear pairTwo angles form a linear pair if they are supplementary and adjacent.
What is vertical angle theorem?
Why We Must Know the Vertical Angle Theorem This theorem says that when two straight lines intersect, they form two sets of linear pairs with congruent angles. It also means that the adjacent angles formed by the intersection of these two lines are supplementary, or equal to 180 degrees.
Are a pair of vertical angles acute?
Vertical angles are two nonadjacent angles formed by two intersecting lines. You can use the corner of a piece of paper to see that ∠ZVY and ∠WVU are less than right angles. Therefore, and are acute vertical angles.

How do you prove two vertical angles are equal?
Why are vertically opposite angles equal?
Intersecting lines are lines that cross each other. The point where they meet is called a vertex. When two lines intersect, the opposite (X) angles are equal. … These X angles are called vertically opposite angles because they are opposite each other at a vertex.
