Ascalene triangle has symmetry with respect to a line containing an altitude of the triangle.. true or false?

So the answer is False

Step-by-step explanation:

A scalene triangle has no equal sides so it has no lines of symmetry as a line of symmetry would divide the triangle evenly. Therefore, the answer is never. A scalene triangle NEVER has symmetry with respect to a line containing an altitude of the triangle.

Hope this helps! ;-)

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

3100
