Step-by-step explanation:
DE is the vertical line x=1. It extends between y=2 and y=7, a distance of 5 units.
EF is the horizontal line y=7. It extends from x=1 to x=4, a distance of 3 units.
Then the perimeter of half the rectangle is 5+3 = 8 units.
The perimeter of the rectangle is 2·8 = 16 units.
Not all triangles have right angles. A triangle is simply a closed figure with three sides and three angles, the sum of the degrees of which add up to 180°.
For instance, an equilateral triangle will will have all three angles equal to each other (60°, 60°, 60<span>°).
Some triangles may have right angles (90</span><span>°), but not all do.
