Tell me the Characteristics of a Reflection

Mathematics
2 answers:
Anna007 [38]2 years ago

Answer:

Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. Light reflects from a smooth surface at the same angle as it hits the surface.

Answer:

Hi, There!

Part A: tell me the Characteristics of a Reflection

There are several important characteristics of a reflection:

  • A reflection maps a line to a line, a ray to a ray, a segment to a segment, and an angle to an angle. Each piece of the original pre-image is exactly the same in the image.
  • A reflection preserves lengths of segments. The length of a line segment will be the same in a reflection.
  • A reflection preserves degrees of angles. The angles of the image are congruent to the angles in the pre-image.

Part B:

Rigid transformation: Moving a figure so that it is in a new location but has the same size, shape, and area.  A mathematical reflection is a type of rigid transformation

Part C:

what is Line of reflection: The line over which a pre-image is reflected to create a new image

Help please! Calculate the exact value of cos (a-b) given that sin a= 12/13 with pi/2
zloy xaker [14]

Answer:

56/65

Step-by-step explanation:

First, we know that cos(a-b) = cos(a)cos(b) + sin(a)sin(b)

We know what sin(a) and sin(b) are, and to get cos(a), we can take the equation sin²a + cos²a = 1

Thus,

(12/13)² + cos²a = 1

1 - (12/13)² = cos²a

1- 144/169 = cos²a

cos²a = 25/169

cos(a) = 5/13

Similarly,

(3/5)² + cos²b = 1

1 - (3/5)² = cos²b

1 - 9/25 = cos²b

cos²b = 16/25

cos(b) = 4/5

Our answer is

cos(a-b) = cos(a)cos(b) + sin(a)sin(b)

cos(a-b)  = (5/13)(4/5) + (12/13)(3/5)

cos(a-b)  = 20/65 + 36/65

cos(a-b)  = 56/65
