Mathematics

leva [86]2 years ago

\sqrt{\cfrac{16}{49}}\implies \cfrac{\sqrt{16}}{\sqrt{49}}\implies \cfrac{\sqrt{4^2}}{\sqrt{7^2}}\implies \cfrac{4}{7}

hmmm 4/7 looks like a "ration" or fraction that is, so, if it moves like a ration and dances like a ration and runs like a ration, it ain't no duck, it must be a rational then.

Need help ASAP!! Write an informal proof to show triangles ABC and DEF are similar.
yaroslaw [1]

Answer:

Δ ABC and Δ DEF are similar because their corresponding sides are proportional

Step-by-step explanation:

Two triangles are similar if their corresponding sides are proportional which means the corresponding sides have equal ratios

In the two triangles ABC and DEF

∵ AB = 4 units

∵ DE = 2 units

∴ \frac{AB}{DE}=\frac{4}{2}=2

∵ BC = 6 units

∵ EF = 3 units

∴ \frac{BC}{EF}=\frac{6}{3}=2

∵ CA = 2 units

∵ FD = 1 units

∴ \frac{CA}{FD}=\frac{2}{1}=2

∴ \frac{AB}{DE}=\frac{BC}{EF}=\frac{CA}{FD}=2

∵ All the ratios of the corresponding sides are equal

∴ The corresponding sides of the two triangles are proportional

∴ Δ ABC is similar to Δ DEF
