Iwill give question 3: the figure below shows a shaded region and a nonshaded region. angles in the figure that appear to be right angles are right angles. what is the area, in square feet, of the shaded region? what is the area, in square feet, of the nonshaded region?

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.
