Question

Translate triangle abc with vertices a (3,5), b(4,1), and c(1,2) 2 units left and 5 units down

Answer 1

• A(3,5)
• B(4,1)
• C(1,2)

2 units left means x is deducted by 2

5 units down means y is deducted by 5

So the rule is

• (x,y)=(x-2,y-5)

New coordinates

• A'(1,0)
• B'(2,-4)
• C'(-1,-3)

Answer 2

Below in bold.

Explanation:

The vertices of the new triangel are:

A' = (3-2, 5-5) = (1, 0).

In the same way:

B' = (2, -4)

C' = -1, -3).
