34. Prove that an altitude of an acute scalene triangle cannot bisect the angle from whose vertex it is drawn.

Consider parallelogram ABCD in the diagram.  The dotted lines are extensions of the sides of the parallelogram. How could you prove ∠CAB≅∠CDB? Choose the answer that best fills each blank ( -- ). First, ∠CDB≅∠DBE because they are --. Next, ∠DBE≅∠CAB because they are --. By -- ∠CAB≅∠CDB. ANSWER CHOICES ( you can only use one per blank. ) a.) consecutive interior angles. b.) alternate interior angles. c.) alternate exterior angles. d.) consecutive alternative angles. e.) the reflexive property. f.) the transitive property. g.) corresponding angles.

1. Is this a correct claim 2. Do the lengths 91, 312, and 325 form a right triangle?

Prove synthetically that the angle bisectors of the interior angles of a triangle are concurrent at a point that is equidistant from the sides of the triangle

which theorem or postulate can be used to prove that these two triangles are similar: SAS~, AA~, Not~ or SSS~ see attached
