How to write a triangle proof
WebIn triangle ABC, the midpoints of BC, CA, and AB are D, E, and F, respectively. Find the value of EF, if the value of BC = 14 cm Solution: Given: BC = 14 cm If F is the midpoint of AB and E is the midpoint of AC, then using the midpoint theorem: EF = 1/2 (BC) Substituting the value of BC, EF = (1/2) × 14 EF = 7 cm Therefore, the value of EF = 7cm.

WebThe end of a proof should come at the end, not at the beginning. Of course, I’ve deliberately made it sound really obvious there. But here’s a more illuminating way of putting it: The proof should end with the thing you’re trying to prove. The proof should not begin with the thing you’re trying to prove.
