Answer:
First option: Square with diagonals
and
.
Fifth option: Segment is parallel to segment
.
Step-by-step explanation:
We know that a square is quadriteral whose sides are equal.
By definition, a square has the following properties:
1) Its four sides are congruent.
2) The diagonals are congruent.
3) The angles formed by the intersection of the diagonals measure 90 degrees.
4) The opposite sides are parallel.
5) Each internal angle measures 90 degrees.
Notice in the figure that:
- The diagonals of the square
are:
and
.
and
are opposite sides, therefore, they are parallel.
Answer:
D = 0; one real root
Step-by-step explanation:
Discriminant Formula:
First, arrange the expression or equation in ax^2+bx+c = 0.
Add both sides by 9.
Compare the coefficients so we can substitute in the formula.
- a = 1
- b = 6
- c = 9
Substitute a = 1, b = 6 and c = 9 in the formula.
Since D = 0, the type of solution is one real root.
