Rotation around the origin clockwise by 90 degrees does not change the size of the triangle
That means triangle 1 and triangle 2 have the same sides, same angles
Then their perimeters and areas are equal
Reflection about a line does not change the size of the triangle
That means triangle 1 and triangle 2 have the same sides, same angles
Then their perimeters and areas are equal
Let us find the correct option
1) The angle measures of triangle 2 is equal to the angle measures of triangle 1 --- TRUE
2) The angle measures of triangle 2 is less than the angle measures of triangle 1 --- FALSE
3) The perimeter of triangle 2 is equal to the perimeter of triangle 1 ---- TRUE
4) The perimeter of triangle 2 is less than the perimeter of triangle 1 ---- FALSE
