Transformation involves changing the position and size of a shape.
The true statements are:
- ∠m≅∠m'
- Δlmn≅Δl'm'n'
- The coordinates of n" are .N''(3,-1.5)
The complete question is as follows:-
The composition do,0.75(x,y) ∘ do,2(x,y) is applied to △lmn to create △l''m''n''. which statements must be true regarding the two triangles? check all that apply. ∠m ≅ ∠m'' △lmn ~ △l''m''n'' △lmn ≅ △l''m''n'' the coordinates of vertex l'' are (-3, 1.5). the coordinates of vertex n'' are (3, -1.5). the coordinates of vertex m'' are (1.5, -1.5).
<h3>What is translation?</h3>
The process of changing the location of the image on the coordinate system will be known as the translation.
The coordinates of the triangle are:
L =(-1,2)
M = (-1,-1)
N = ( 2,-1)
The transformation rule is given as:
do 0.75 (x,y) 2 (x,y)
The transformation rule is a dilation by a factor of 0.75, and then a factor of 2.
Uniform dilation changes the size of a shape, but the angles remain unchanged. This means that:
∠l≅∠l''
∠m≅∠m''
∠n≅∠n''
Δlmn⇒Δl'm'n'
The above highlights mean that:
The angles of both triangles are congruent
The triangles are similar
Next, we apply the rule on the coordinates of the triangle
L'' = 0.75 x 2 x (-1,2)
L'' = ( -1.5,3)
M'' = 0.75 x 2 x (-1,-1)
M'' = ( -1.5 , -1.5)
N'' = 0.75 x 2 x (2,-1)
N'' = (3 , -1.5)
Hence, the true statements are: The coordinates of n" are.
- ∠m≅∠m'
- Δlmn≅Δl'm'n'
- The coordinates of n" are . N''(3,-1.5)
