construct a perpendicular

Find the midpoint of each of the 3 sides of the triangle and extend lines from each point.

Step-by-step explanation:

take a compass and put the needle on the a point of the triangle and extend the graphite more than half way on one of the sides and draw a mark. Repeat on the other point of that side and the marks should intercept twice. draw a line along those to points you just created. This creates a perpendicular bisector. You can do this on all the sides and the three vertical bisectors should intercept.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

i think the correct option is the second option.
