In this lesson, you learned new formulas to find the area of a triangle. How are these formulas different from the commonly know

Yuki888 [10]

Aside from the conventional formula for triangle, A=½bh which is only applicable to problems where the base and height are already given and the triangle is a right triangle having a degree of 90. There are some formulas in getting the area of a triangle:

>Given three sides of the triangle, use Heron's Formula
A= sqrt(s(s-a)(s-b)(s-c))
s= (a+b+c)/2
>Given two sides with an included angle
Area = 1/2 ab sin (tetha)
tethat should be in degrees

Answer:

(B)A': (p, m) and B': (z, −w)

Step-by-step explanation:

Line AB has a negative slope and goes through points (-m, p) and (w, z).

Line A'B' has a positive slope and intersects with line AB.

Definition: Two lines are perpendicular if the product of their slopes is -1.

Slope of AB

$m_1=\dfrac{z-p}{w-(-m)} \\m_1=\dfrac{z-p}{w+m}$

From the options, we consider the coordinates whole slope multiplied by the slope of AB gives a result of -1.

In Option B: A': (p, m) and B': (z, −w)

Slope of A'B'

$m_2=\dfrac{-w-m}{z-p} \\m_2=\dfrac{-(w+m)}{z-p}$

The product of the slopes

$m_1m_2=\dfrac{z-p}{w+m}\times \dfrac{-(w+m)}{z-p} =-1$

Therefore, the coordinate for points A' and B' which would help prove that lines AB and A'B' are perpendicular is A': (p, m) and B': (z, −w).

You can try to calculate the slope of the others. They would not satisfy this condition.
