With a two-column proof you write what you know on the left side and on the right side you say how you know that.

Example from source site:

A proof is meant to take the reader from a hypothetical to a conclusion,
showing why we should have no doubt of the truth.

...A\ w/E
.......\/
.....x/\y
...../ z\
..D/.....\B

Hypothetical: If segments AB and DE intersect,

Conclusion: then the opposite angles (x&y, w&z) formed by the intersection are equal.

This is proven by:

AB intersects DE forming vertical angles x and y, z and w
Two column:
x+z=180 degrees...definition of supplementary
y+z=180 degrees...definition of supplementary
x+z=y+z......substitution
x=y..............subtraction

feels like your college provides one geometry classification that would not incorporate doing proofs, and a greater rigorous (greater durable) classification that does. i've got self belief you're interior the greater durable classification.perhaps your grade would be greater heavily weighted, or maybe yours is the path that satisfies the faculty geometry requirement. you ought to talk on your college counselor and in simple terms ask. Or seem on the faculty website.
