The opposite angles formed when two lines intersect are always equal to each other.
According to the law of reflection, the angle of incidence is always equal to the angle of reflection.
Answer Statement: B
Suppose there is a light ray that falls on a plane surface or mirror and gets reflected. If we draw a normal going through the point where both the rays (incident and reflected rays) meet, we can easily observe that they both make an angle with this normal N say i and r, respectively.
With specific observation it's concluded as the statement and hence, the law; that the angle of incidence i and the angle of reflection r are equal with respect to the normal drawn at the point the point they both meet when the all of them are correspondent to the same surface.
Angle of Incidence = Angle of reflection
Now, coming to the point that what are the other angles thus formed along with the surface, can be calculated by simply subtracting the angle of incidence and the angle of reflection from 90 degree, being the normal on the plane surface or the mirror.
Both the angle doesn't necessarily made a 180 degree angle. In fact, it's quite difficult to think about such an angle. Neither both the angles are of 90 degree. Hence, their difference may also vary.
answer: the light rays
explanation: b/c these are how we see the light it hits our eyes and that light bounces back in forth so we constantly see that light
We have to find the true statements
A. Adjacent angles are always complementary.
It is not true. Because it is not necessary that sum of adjacent angle is always equal to 90 degrees.
B.The sum of the measures of complementary angles equals 90 degrees.
We know that complementary angle:The pair of angles whose sum is equal to 90 degrees is called complementary angles.
Hence, option B is true.
C.Adjacent angles are always equal in measure.
It is not true.Because it is not necessary that adjacent angles are always equal in measure.
D.The sum of the measures of supplementary angles equals 90 degrees.
It is not true because sum of supplementary angles equals to 180 degrees not 90 degrees.
Vertical angles are angles that are opposite each other when two lines intersect each other. The two pairs of opposite angles are equal to each other. The two pairs of neighboring angles are supplementary, meaning they add up to 180 degrees.
The correct statement about vertical angles is that they are always equal in measure. This also implies they are congruent. Therefore, the correct answer is C.
For example, if a vertical angle measures 140 degrees, it means the other angle will also measure 140 degrees.Further Explanation
Vertical angles are always equal in measure, they are very special angle and they are congruent to one another.
Vertical angles are non-adjacent angles and they are formed when 2 lines intersect. In vertical angles, all the pairs of the angles are opposite each other.
The angles that opposite another are called supplementary and their sum in total is 180 degrees.
However, there are four different types of angles and these includeVertical angleComplementary angleSupplementary angleAdjacent angle
Complementary angle: they are 2 angles that measure 90 degrees, that is they form a right angle
Supplementary angle: they are 2 angles that measure 180 degree
Adjacent angle: they are 2 angles that have common vertex (corner point) and a common side. Also, adjacent angles don’t overlap. When 2 angles have a corner point and a common side, it implies that the 2 angles shared the vertex point and the side.
Therefore, the correct statement about vertical angles is that they are always equal in measure (they are congruent)
