Geo Question: Find the perimeter of a triangle with an inscribed circle. ED = 58, DC = 80, and ET = 26. Answer choices are a. 218 b. 164 c. 212 d. 196 I was thinking that ED and ET are ~ since they are tangent and come from point E, so the answer would be 196
I thought that ED ~ EC, so 58 + 58 + 80 = 196, but EC looks longer in the picture.

A circle would mean the points of intersection with the triangle are all equidistant from the centre of the circle - use the three angle bisectors here.

How do I use the angle bisectors to find the missing segment TC?
