Hi! I am having trouble drawing an angle with a geometric compass. The question states:
"Construct an angle with each given measure and label it. Remember, you may use only your compass and straight edge. NO PROTRACTOR!"
a) 90 degrees
b) 45 degrees
c) 135 degrees
I have construscted a 90 degree angle and two 45 degree angles to make a triangle, but idk how to make it 135 degrees because isnt a triangle just 180? Does the question really want me to make a triangle or am i just over thinking it?

You already have 90 and 45.
So put them together to make 90+45 = 135 degrees.
