Step-by-step explanation:
First check if the triangle is right.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side =
and (
)² = 12
2² + (
)² = 4 + 8 = 12
Thus the triangle is right → C
This is an octagon, which has 8 sides.
the angle of rotation is 360/8 = 45°
