True or false
the point of concurrency for perpendicular bisectors of any triangle is the center of the circumscribed circle.

This is true
Perpendicular lines = circumscribe
angle bisect = incircle
altitude = orthocenter
median = centriod

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
