The vertices of a quadrilateral in the coordinate plans are known. How can the perimeter of the figure be found?
1 answer:
Answer:
The perimeter can be found by calculating lengths of sides using distance formula and then adding up the lengths
Step-by-step explanation:
If the vertices of a quadrilateral are known in the coordinate plane, the vertices can be used to determine the lengths of sides of quadrilateral. The distance formula is used for calculating the distance between two vertices which is the length of the side
after calculating all the lengths of four sides using their vertices, they can be summed up to find the perimeter ..

Answer:
slope = -
Step-by-step explanation:
Differentiating implicitly with respect to x
2x + 2y = 0
2y = - 2x
= -
= -
is the measure of the slope of the tangent
rearrange equation to find corresponding y-coordinate of x = - 2
y² = 16 - 4 = 12 = 2 ⇒ y = ± 2
using x = - 2, y = - 2, then
= -
= -
