Question

quickstudent · Answer

question attached. my answer:
RA is twice as big as EA: 3.5 * 2 = 7

RA = 7

AH is twice as big as AC: 6 * 2 = 12

AH = 12



7/3.5 = 2

12/6 = 2

According to the SAS Similarity Postulate, the two triangles are similar, because two of their sides are proportional, and the included angles are both right angles, so they are congruent.

I agree that the two triangles are similar, but not that they are congurent.

joannablackwelder · Answer

To be congruent, they have to have the same length of two sides and the included angle, not just proportional.

quickstudent · Answer

I meant that the angles were congruent, not the triangles.

joannablackwelder · Answer

Ah, I see what you mean. Yes, that is true. :-) And your side lengths are correct.
