When designing a pattern, Erica rotated a triangle 90 degrees about the midpoint of one side to create a second triangle. If the area of the original triangle is 48 square inches, what is the area of the second triangle?
the same -- rotation does not change area.
To find the area of the second triangle, we need to understand how rotating a triangle affects its area.
When you rotate a shape by 90 degrees about a point, the area of the shape does not change. This is because rotation does not affect the size or shape of the object, only its orientation.
So, the area of the second triangle will also be 48 square inches, the same as the original triangle.
