Question

The directions are with the pic below. It’s 4 choices. I’m sending 2 over now and I’ll send the other 2 pics right away. Couldn’t all fit on page.

Answer 1

Solution

The coordinate of the vertex of a triangle is shown below

$J(1,-2),K(3,-2),L(2,-1)$

Triange JKL is rotated 270 degree counterclockwise with the origin at te centre of rotation

When rotating a point 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x). This means, we switch x and y and make x negative

$\begin{gathered} J(1,-2)-\longrightarrow J^1(-2,-1) \\ K(3,-2)-\longrightarrow K^1(-2,-3) \\ L(2,-1)-\longrightarrow L^1(-1,-2) \end{gathered}$

Therefore the correct answer is Option B
