The coordinates of the vertices of triangle LMN are L(-3, 4) M(-2, 0) and N(6, 2) Is triangle LMN a right triangle?

Prove your answer without graphing. You can use a graph to help you, but you must prove it using slope
(Hint: RT Tri. have one 90 degrees angle with perpendicular lines - slopes of those lines are opposite reciprocal)

answer: 180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
