E 3. If the measure ZLOE = 4. ITLE=EV and LE = 8 m, then LV = 5. IZLOE - 6x-2 and ZVOE= 5x+4, then the measure of ZLOV is What I Have Learned Activity 5: "III Show what I've Learned" Directions: Follow the procedure. Write your answer inside the box. The bisector of the vertex angle of an isosceles triangle is perpendicular to the midpoint. Procedure: 1. Draw an isosceles AABC. 2. Draw the bisector BE of the vertex ZB which intersects AC at E. 3. Prove that the two ABEA and ABEC are congruent. 4. Show that E is the midpoint AC.​
