To solve a proof, you need to distinguish which is the hypothesis and which is the conclusion. The hypothesis is the starting point and the conclusion is the ending point. We go from hypothesis to conclusion. A conditional statement can be written as If A, then B. Where A is the hypothesis and B is the conclusion.
For example, take this theorem.
If two sides of a triangle<span> are congruent, then the angles opposite those sides are congruent. </span> We go from Two sides of a triangle are congruent to the angles opposite those sides are congruent.
The first statement's reason is pretty much always Given.
Statement | Reason 1. Two sides of a triangle are congruent 1. Given .... After a bunch of steps 3. the angles opposite those sides are congruent. 3. Your postulate of definition of what reason you need to complete the last step.
volume of a rectangular prism is length * width * height, since the shape is 3D, or multi-demensional. you take all three numbers and multiply them together :) in this case its 7, 3, and 4. 4 * 3 is 12, and 12 * 7 is 84 :)
