As some of my peers might know‚ geometry is definitely not my favorite subject in math. I have always struggled with geometry‚ especially with memorizing formulas to solve problems such as finding volume‚ surface area and more. I always found formulas to be such a bother and even after learning one and mastering it somewhat‚ I usually ended up forgetting the formula. Fortunately‚ the formulas that I had the most trouble with‚ being volume‚ surface area‚ and area‚ have finally began to stick with
