Perpendicular lines create obtuse angles where they intersect.
True
False

The answer is false

Step-by-step explanation:

Perpendicular lines create four 90 degree angles thus if you connect the edges you make a square that has four 90 degree corners. Lines that can crate obtuse angles are called intersecting angles. And parallel never touch so they don't make any angles

e) none of the above because the measure of angle cba is 101°

good luck on your studies! : )
