Question

describe the isometry that is 90 degrees counterclockwise rotation about M followed by 90 degrees counterclockwise rotation about L. Picture to follow

Answer 1

so this is what I put.. isometry is a transformation that keeps the size and shape of the geometric figure, so if we rotate this counterclockwise by 90 degrees ...the rotation is also an isometry and maps the square to itself... So since we have triangles if I rotate this by 90 degrees counter clockwise I should retain my square.

Answer 2

and also retain the shape of my triangles inside the square... since Point I is the center and doesn't move.
