Answer:
The answer for number 1 is "Right", because it is a 90 degree angle.
The answer for number 2 is "Acute", because it is less than a 90 degree angle, about 40 to 60 degrees.
The answer to number 3 is "Straight" because it is more than a 90 degree angle but its a straight line.
The answer to number 4 is "Reflect" because the angle measure is on the outside instead of the inside.
I hope this will help you :)
