Given:
Consider triangle ABC is rotated 90 degrees counterclockwise and then translated 3 units up to form triangle A'B'C'.
To find:
The transformation that can be used to map each point (x,y) on Triangle ABC to its corresponding point on Triangle A'B'C'.
Solution:
If a figure rotated 90 degrees counterclockwise, then
If a figure translated 3 units up, then
If triangle ABC is rotated 90 degrees counterclockwise and then translated 3 units up to form triangle A'B'C', then the rule of transformation is
Therefore, the required rule of transformation is .

Answer:
Therefore area of a triangle whose vertices are (0,0), (4,2), (-1,2) is
5 units².
Step-by-step explanation:
Given:
Let the vertices be,
point A( x₁ , y₁) ≡ ( 0 , 0)
point B( x₂ , y₂) ≡ (4 , 2)
point C(x₃ , y₃ ) ≡ (-1 , 2)
To Find:
Area of Triangle = ?
Solution:
If the Vertices A( x₁ , y₁), B( x₂ , y₂) and C(x₃ , y₃ ) then the Area of Triangle is given by
Substituting the values we get
Therefore area of a triangle whose vertices are (0,0), (4,2), (-1,2) is
5 units².
