Answer :
Congruent shapes are shapes that have similar and equal side lengths and angles
The transformation that would result in two congruent triangles is: (b) vertex x should be moved down 10 units
From the diagram (see attachment)
- The base of both triangles are equal i.e. YZ = 4 units
- The first triangle has a height of 7 units
- Triangle XYZ has a height of 3 units
So, the transformation that makes both triangles to be congruent must be applied to the vertex X
Vertex X must either be moved up or down
The number of units (k) up is:
[tex]\mathbf{Height\ of\ XYZ + k = Height\ of\ first\ triangle}[/tex]
So, we have:
[tex]\mathbf{3 + k = 7}[/tex]
Collect like terms
[tex]\mathbf{k = 7 - 3}[/tex]
[tex]\mathbf{k = 4}[/tex]
The number of units (k) down is:
[tex]\mathbf{k - Height\ of\ XYZ = Height\ of\ first\ triangle}[/tex]
So, we have:
[tex]\mathbf{k - 3 = 7}[/tex]
Collect like terms
[tex]\mathbf{k = 7 + 3}[/tex]
[tex]\mathbf{k = 10}[/tex]
This means that:
Vertex x should be moved 4 units up or 10 units down
Hence, the true statement is: (b) vertex x should be moved down 10 units
