Which statement about triangles is true?

all right triangles are also isosceles triangles.

all acute triangles are also equilateral triangles.

all equilateral triangles are also acute triangles.

some obtuse triangles are also right triangles.

All acute triangle are also isosceles triangle

all but the second one

step-by-step explanation:

cuz that one goes over 180

mark brainliest

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
