The triangles here are each obtained by applying rigid motions to triangle 1.
1 answer:
Rigid transformation is a transformation that does not change the measure of the side lengths and the angles.
- Triangles 3, 5 and 7 are translations of triangle 1
- Triangles 2, 4 and 6 are not translations of triangle 1
From the question (see attachment), we have the following observations
- Triangles 3, 5 and 7 have the same orientation as triangle 1
- Triangles 2, 4 and 6 are reflected versions of triangle 1
Translation and reflections are both rigid transformation.
However, when a shape is translated, the <em>resulting shape </em>must have the same orientation as the original shape.
This means that:
- <em>Triangles 3, 5 and 7 are translations of triangle 1</em>
- <em>Triangles 2, 4 and 6 are not translations of triangle 1</em>

Answer:
C. 33 square feet.
Step-by-step explanation:
to get the area of irregular polygon.
divide the area into two parts (see attached image)
total area = A1 + A2
where A = 1/2 base x height
total area = ( 1/2 * 6 * 8) + (1/2 * 6 * 3)
total area = 24 + 9
total area = 33 square feet.
therefore the answer is C. 33 square feet.
