In addition to the facts in the diagram, which other statements are necessary to prove that ∆abc is congruent to ∆efg by the asa criterion? i. m∠b = m∠f ii. bc = fg iii. m∠a = m∠e iv. fg = 3 v. m∠b = m∠e a. i or iv only b. i only c. i and iii only d. iii or v only

let's recall that ASA is just the acronym for Angle Side Angle.

so we really need two angles and a side between them.

now, from the graph, we can see that AB = 2 = EF, so AB = EF.

now, if those angles cornering those sides can just be equal, that'd be grand, namely if ∡A = ∡E and ∡B = ∡F, then we'd have the ASA congruence.

what's that
