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

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

1010: 3030

is it i think
