Question

If triangle ABC was rotated 90 degrees counterclockwise about the origin, what would the ordered pairs be for B'''?

Answer 1

Point B is
`(-1,2)`

Explanation:

Given: A triangle ABC was rotated 90 degrees counterclockwise

To find: coordinates of the point B

Solution:

A triangle is three - dimensional figure that has three sides, three vertices and three angles.

Counterclockwise refers to the direction opposite to the direction of movement of hands of the clock.

As triangle ABC was rotated 90 degrees counterclockwise about the origin, point B is
`(-1,2)`
