Question

Please help me im stuck and the selected answer is not wrong or right i dont know

Answer 1

No these triangles are not similar.

Step-by-step explanation:

Given Information on First triangle :

Base = 3

Height = 8

Given information on Second triangle :

Base = 4

Height = 10

Area of a Right Angle triangle :

$\frac{base \times height}{2}$

Area of First triangle :

$\frac{3 \times 8}{2} = \frac{24}{2} \\ \\ = 12$

Area of Second triangle :

$\frac{4 \times 10}{2} = \frac{40}{2} = 20$

Their Ratio :

$12:20 = \frac{12}{20} \\ = \frac{3}{5}$

So I guess no, the triangles are not similar.
