Answer:
1-Two angles are called complementary when their measures add to 90 degrees
EXAMPLES= 30 AND 60 DEGREES ANGLE
40 AND 50 DEGREES ANGLE
80 AND 10 DEGREES ANGLE
2-An acute angle is an angle that measures less than 90 degrees.
EXAMPLES = 40 DEGREE ANGLE
10 DEGREE ANGLE
45 DEGREE ANGLE
You see how these 2 angles marked are both inside the 2 parallel lines?
And they are on opposite side of the transversal, the line crossing the 2 parallel lines?
These 2 angles are alternate interior angles and they are equal, I think you can do the last part by yourself.
