Question

Triangle $ABC$ is congruent to triangle $DAE$. $ACE$ is a straight line. Given that $AD = 8.7\text{ cm}$, $CE = 2.2\text{ cm}$, $DE = 6.8\text{ cm}$, angle $ADE = 70^\circ$ and angle $ACB = 65^\circ$. Find $AE$.[1] Find angle $EAD$.[1] Tom states that $AB$ is parallel to $DE$. Show, with calculations, whether you agree with Tom. [2]

Accepted Answer

(a) $9\text{ cm}$. (b) $45^\circ$. (c) No: $70^\circ\ne65^\circ$, so $AB\not\parallel DE$.
