A triangle
The measure of the First angle of
is 25 degree less than the measure of the
Second angle. The measure of the third angle
of the triangle is triple the measure of the
second angle.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
