In this lesson we look at different ways to prove that lines are parallel. We then incorporate these methods into longer proofs ... In this lesson we will investigate what conclusions can be drawn about geometric figures based on what we are told (given) about ... In this lesson we look at the SAS, ASA, and SSS Theorems for proving that two triangles are congruent. Simple proofs involving ... We first prove the AAS Theorem for triangle congruence based on the ASA Theorem. We then use both theorems to investigate ... The axioms of equality and congruence are discussed in this lesson along with their simple use in proof with both line segments ... In this lesson we explain the idea of CPCTC reasoning in geometric proof. We will then use this reasoning in a variety of simple ...
In this lesson we examine basic addition and subtraction proofs with segment lengths and angles. We then use these in longer ... In this lesson we review the major properties of parallel lines, such as alternate interior angles and corresponding angles being ... In this lesson we prove the hypotenuse-leg theorem for triangle congruence and then use it in a variety of proofs including ...
