Answers for the lesson “Solve Right Triangles”
... Find the measure of ACE using the sine ratio, then find the measure of ACB because it is supplementary to ACE. The Law of Cosines allowed me to find AB and then I used the Law of Sines to find the measure of ABC. ...

Triangles
... External & Internal angles of 2d regular shapes All of the external angles of regular 2d shapes add up to 360º We use this information to find the external (outside) angle of the shape. e.g. a triangle has 3 sides so each of the external angles are ...

... triangles, AB and AC, are congruent. Also, AE is a leg for both triangles and AE ≅ AE by the Reflexive Property of Congruence. Thus, by the HypotenuseLeg Congruence Theorem, ∆AEB ≅ ∆AEC. Similar reasoning can be used to prove that ∆AEC ≅ ∆AED. So, by the Transitive Property of Congruent ...
