When a figure can be rotated 180 degrees and still looke the same
When u rotated a figure 180 is the reflection the same
Is Multiplication of 2 X 2 matrices associative
All matrix multiplications are associative
Always .. .A+
Multiplication of 2 X 2 matrices is commutative
Is rotation scalar or vector
Rotation is a vector having a direction and magnitude.
If in ABC B is equal to C what kind of triangle is ABC
Triangle ABC would be an isosceles. An isosceles triangle is
defined as having two sides of equal length. This would also mean,
then, that two angles in the triangle are also the same.
In triangle ABC what is the length of line C if A equals 5 and B equals 10
What are the coordinates of the vertices of triangle a'b'c' after triangle ABC is dilated using a scaling factor of 3
Find the coordinates of the vertices of triangle a'b'c' after
triangle ABC is dilated using the given scale factor then graph
triangle ABC and its dilation
A (1,1) B(1,3) C(3,1) scale factor 3
Can a matrix with dimensions of 2 X 4 be added to another matrix with dimensions of 2 X 5
No. Matrix addition (or subtraction) is defined only for
matrices of the same dimensions.
1 3 is reflected over the y axis What are the coordinates of the image
Can a matrix with dimensions of 3 X 6 be added to another matrix with dimensions of 6 X 3
No, but it can be multiplied:
The new matrix is 3x3. EG:
100100 100 200
010010 x 010 = 020
001001 001 002
100
010
001
How do the coordinates of a point change when it is reflected over the x-axis
Reflecting the the x-axis (line y=0) leaves the x-coordinate
unchanged and negates the y-coordinate:
(x, y) -> (x, -y)
For example:
(1, 2) -> (1, -2)
(3, -4) -> (3, 4)
Can a matrix with dimensions of 2 X 4 be added to another matrix with dimensions of 2 X 4
If A B C and D are points on a number line B is the midpoint of Ac what is the coordinate
The 'x' coordinate of B is the average of the 'x' coordinates of
A and C.
The 'y' coordinate of B is the average of the 'y' coordinates of
A and C.
Multiplication of 2x2 matrices is commutative
No. Multiplication of matrices is, in general, non-commutative,
due to the way multiplication is defined.
How many degrees has the minute hand moved through in 1 over 6 of half a rotation
1/6 of half a rotation = 1/12 of a rotation = 1/12 of 360
degrees = 360/12 = 30 degrees.
Triangle abc has vertices a 1 2 3 b 4 0 5 and c 3 6 4 Show that abc is a right triangle
Your question doesn't seem to make any sense but if the sides of
the triangle are 3, 4 and 5 then it is a right angle triangle
because it complies with Pythagoras' theorem.
What is the image of point 3 and 5 if the rotation is 180 degrees
What is the image of point (3, 5) if the rotation is
What does reflection over the y-axis mean
Example: if you have a point with the coordinates (2,4), a
reflection over the y-axis will result in the point with
coordinates (-2,4).
What is the image of point 3 5 if the rotation is 90
What is the reflection image of 5 -3 across the y axis
The y-axis is the symmetry line, so that (5, -3) and (-5, -3)
are symmetric points.
What is the image of point (4 3) if the rotation is -180º
Which graph shows a reflection across the x-axis
y = -f(x) is a reflection of y = f(x) in the x axis.
What is the line over which a figure is reflected
It is the axis of reflection.
What is the A coordinate Triangle ABC is reflected over the x-axis. Triangle ABC has points A (10 2) B (8 3) and C (6 4). What is the A' coordinate
