Discussion topicin this unit, you worked with geometric proofs. aproof is a logical sequence of justified conclusionsthat lead from a hypothesis to a final conclusion. in your opinion, why are mathematical proofsimportant? suppose that a conclusion within a proof isn'tjustified or is inaccurate. in geometry, what mightbe the consequences of the inaccuracy? now think about different kinds of proofs that takeplace outside the world of geometry, and list a fewexamples. what might be the consequences ofhaving an unjustified conclusion surface in suchproofs? who might be affected and how?

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

hi there!

the answer will be d: 2

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
