Geometric Proofs: Part 1 of 3 of learning to solve proofs

The video tutorial explains the process of proving geometric properties using two examples. The first example involves proving that a segment AC is twice the length of another segment DC, given that BD is a bisector. The second example demonstrates proving that an angle is a right angle by using the definition of perpendicular lines. The tutorial emphasizes the importance of starting with given information, using logical reasoning, and applying definitions and substitutions to reach a conclusion.

What is the importance of writing down the given information in a proof?
