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.

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 :

`(base * height)/(2)`

Area of First triangle :

`(3 * 8)/(2) = (24)/(2) \\ \\ = 12`

Area of Second triangle :

`(4 * 10)/(2) = (40)/(2) = 20`

Their Ratio :

`12:20 = (12)/(20) \\ = (3)/(5)`

So I guess no, the triangles are not similar.
