Q.1 (A)(1) If Δ ABC sim Δ DEF , m∠ B = 60^° , then m∠ E = .................... A. 30º B. 60º C. 90º D. 45º

Answer: B. 60º Answer: (B) 60º Corresponding angles of similar triangles are equal, and ∠ B of Δ ABC corresponds to ∠ E of Δ DEF (the order of letters in Δ ABC sim Δ DEF ). So m∠ E = m∠ B = 60^° .

If \(\Delta ABC \sim \Delta DEF\), \(m\angle B = 60^\circ\), then \(m\angle E\) = ....................

Answer: B. 60º

Answer: (B) 60º

Corresponding angles of similar triangles are equal, and \(\angle B\) of \(\Delta ABC\) corresponds to \(\angle E\) of \(\Delta DEF\) (the order of letters in \(\Delta ABC \sim \Delta DEF\)). So \(m\angle E = m\angle B = 60^\circ\).
