I dont get it guys😢

Do you know what similar triangles are?

#

sacred crane Do you know what similar triangles are?

ye syes

sacred crane May 6, 2024, 9:52 AM

#

or rather, proportional ones

#

I think that would be more appropriate for us

#

so if you have two triangles that have the same angles, one version is just a scaled version of the other

#

Not in the proper sense of the triangle proportionality theorem

#

but you get the idea

<KIN is impossible to be 90 degrees, am i seeing something wrong?

sacred crane May 6, 2024, 9:56 AM

#

empty cargo <KIN is impossible to be 90 degrees, am i seeing something wrong?

Why would it be impossible

#

I don't see a reason why

empty cargo May 6, 2024, 9:56 AM

#

sacred crane I don't see a reason why

idk the i'm seeing something wrong

sacred crane May 6, 2024, 9:57 AM

#

Anyway, the point is

empty cargo May 6, 2024, 9:57 AM

#

this looks very not to scale

sacred crane May 6, 2024, 9:57 AM

#

KIN is similar to DIN

sacred crane May 6, 2024, 9:57 AM

#

empty cargo this looks very not to scale

yeah cause it's a sloppy figure

empty cargo May 6, 2024, 9:57 AM

#

mk

sacred crane May 6, 2024, 9:57 AM

#

but I can assure you that such a triangle exists

sacred crane May 6, 2024, 9:58 AM

#

empty cargo mk

to convince you, take a compass and use the midpoint O of [KN]

rigid solar May 6, 2024, 9:58 AM

#

omg thank you

sacred crane May 6, 2024, 9:58 AM

#

draw the circle of center O and of radius ON

#

and shoot a perpendicular to [KN] through D

#

that will give you said figure

sacred crane May 6, 2024, 9:59 AM

#

rigid solar omg thank you

Anyway, back to you

#

KIN is similar to DIN, I want you to explain to me why

#

and after that you can derive the rest of the lengths

rigid solar May 6, 2024, 10:00 AM

#

cuz DIN is a smaller version of KIN and they have the same angle

sacred crane May 6, 2024, 10:00 AM

#

rigid solar cuz DIN is a smaller version of KIN and they have the same angle

"they have the same angles" is a good explanation enough

#

could you tell me what angle is equal to what angle?

rigid solar May 6, 2024, 10:02 AM

#

angle K= angle N and Angle I = angle D

sacred crane May 6, 2024, 10:02 AM

#

yeah, sounds about right

#

and trivially, the last angles are also the same, since they need to sum up to 180° in their respective triangles

#

Now that can help you identify some proportionality relationships

#

between the lengths in the triangles
