Answer 1

you can compare the length of sides of both the triangles...

Answer 2

Answer:

see explanation

Step-by-step explanation:

We can show that Δ ABC and Δ DEF are similar by the SSS postulate

If the ratios of the 3 pairs of corresponding sides are equal , then the triangles are similar.

$\frac{AB}{DE}$ = $\frac{4}{6}$ = $\frac{2}{3}$

$\frac{AC}{DF}$ = $\frac{8}{12}$ = $\frac{2}{3}$

$\frac{BC}{EF }$ = $\frac{5}{7.5}$ = $\frac{2}{3}$

Then by the SSS postulate the triangles are similar

Since the triangles are similar then corresponding angles are congruent, so

∠ D = ∠ A
