Geometry theorem list
WebTheorems. A theorem is a hypothesis (proposition) that can be shown to be true by accepted mathematical operations and arguments. A proof is the process of showing a theorem to be correct. The converse of a theorem is the reverse of the hypothesis and the conclusion. For example, given the theorem “if , then ”, the converse is “if , then ”. WebHarvard Mathematics Department : Home page

WebThe Angle in the Semicircle Theorem tells us that Angle ACB = 90°. Now use angles of a triangle add to 180° to find Angle BAC: Angle BAC + 55° + 90° = 180°. Angle BAC = 35°. So there we go! No matter where that angle is. on the circumference, it is always 90°. drawings of men laying dowWebMathematical Theorems: Mathematical theorems are the statements that have been proven to be true either on the basis of accepted statements such as axioms or on the basis of previously established statements.
