Which description does NOT guarantee that a quadrilateral is a rectangle?

Mathematics
1 answer:
Kisachek [45]3 years ago
8 0

Answer: A

 a quadrilateral with all four angles right

Step-by-step explanation:

A  quadrilateral is a rectangle if a quadrilateral has all four angles right,

a parallelogram with congruent sides

a quadrilateral with diagonals that are congruent and bisect each other

a quadrilateral with all congruent angles. Because a rectangle possesses 2 pairs of parallel sides, 4 right angles at 90°. It has opposite sides which

are parallel and  congruent. And all its angles are congruent.

But a quadrilateral with all four angles right is a description that does NOT guarantee that a quadrilateral is a rectangle. Because this description is also applicable to a square.

Answer:

C

Step-by-step explanation:

since there cant be technically half of someone (i hope not) the domain has to be "whole numbers". hours can be split, so they are "all numbers". well, looking at it again, it is C, since the others can not possibly be correct.

Two perpendicular lines intersect on the -axis. The equation of one line is y- 4x-6=0. Determine the equation of the other line.
Kay [80]

Answer:

y = -\frac{1}{4}x + 6 or y = -\frac{1}{4}x - 0.375

Step-by-step explanation:

For 2 lines to be perpendicular, their slopes must be <u>negative reciprocals</u>. In order to find the perpendicular of y - 4x - 6 = 0:

SLOPE INTERCEPT FORM: y = 4x + 6

SLOPE OF LINE A: m=4

SLOPE OF LINE B (the one you are looking for): m=-\frac{1}{4}

Since I don't know if you meant that they intercept on the x or y axis I will do both.

<u>y-axis</u>

y-6=-\frac{1}{4}(x-0)

y = -\frac{1}{4}x+6

<u>x-axis</u>

y-0=-\frac{1}{4}(x-1.5)

y=-\frac{1}{4}x-0.375
