Which of these are similar triangles?
Hvilken trekant er ensvinklet?So similar triangles are two triangles that have all the same angles.
And all of these are similar triangles.
They must be similar triangles. or the ratio between the corresponding sides must be the same.
Derfor må de være ligedannede trekanter. Forholdet mellem de ensliggende vinkler må altså være det samme.So these are two similar triangles.
Det her er altså 2 ligedannede trekanter.It would always have a 2 to 1 ratio if this had a 2 to 1 ratio and if these are similar triangles.
The classical definition of similar triangles is that all the corresponding angles are equivalent.
So that's a pretty good sign that these are not going to be similar triangles.
Det er et tegn på, at de ikke er ligedannede.We also know that these are going to be similar triangles, that the ratio between corresponding sides is going to be the same.
Det forhold kalder vi en hældning. Vi ved også, at trekanterne er ligedannede. Forholdet mellem de ensliggende sider er derfor ens.So they have two angles in common They're definitely similar triangles.
De har altså 2 vinkler tilfælles, så de er helt sikkert ligedannede.Which of these are similar triangles?
Hvilke af disse er ensvinklede trekanter?What SAS ins ins in the similarity world tells you is that these triangles are definitely going to be similar triangles.
SVS reglen siger så, at de her trekanter uden tvivl vil være ligedannede.They both share that angle there, and so we know that two triangles that have at least two of their angles are, are that at least have two congruent angles,they are going to be similar triangles so we know, we know that triangle, I will write this, triangle ABC, ABC, we went from the unlabeled angle to the right, yellow right angle to the orange angle.
So before we start using any of that ratio stuff, we have to prove to ourselves and prove in general,that these are similar triangles.
Inden vi begynder at kigge på sideforholdene, skal vi bevise,at det er ligedannede trekanter.So these are definitely similar triangles.
De er altså helt sikkert ligedannede.So if you have all three corresponding sides,the ratio between all three corresponding sides are the same then we know that we are dealing with similar triangles.
Hvis vi har alle 3 ensliggende sider,så vil forholdet mellem alle tre ensliggende sider være det samme. På den måde ved vi, at vi har med ligedannede trekanter at gøre.And they're going to be similar triangles.
Det vil sige, at trekanterne er ligedannede.In addition to geometrical theorems with precise proofs, the book includes practical information for surveyors,including a chapter on how to calculate the height of tall objects using similar triangles.
Ud over geometriske teoremer med nøjagtige beviser, bogen indeholder praktiske oplysninger for skibsinspektører,herunder et kapitel om, hvordan man beregne højden af høje genstande, der bruger lignende trekanter.What we know that the ratios of corresponding sites, one of those, each of those similar triangles are going to have to be the same.
Vi ved, at forholdet mellem hver af We have a 90-degree angle there andactually said that by itself is actually enough to say that we have two similar triangles.
Vi har en 90-grader vinkel her, ogvi har derfor nok information til at sige, at vi har to ligedannede trekanter.What I wanna do in this video is See if we can identify similar triangles here.
I Plutarch however recounts the story in a form which, if accurate,would mean that Thales was getting close to the idea of similar triangles.
Plutark dog recounts historien i en form, som, hvis nøjagtige,ville betyde, at Thales fik tæt ved tanken om lignende trekanter.We will we can just work through the math Just using the similar triangles.
Nu kan vi se på matematikken ved at bruge de ligedannede trekanter.And so these angles will also be the same, so they're definitely similar triangles.
De her vinkler vil altså også være ens, og trekanterne er derfor ligedannede.So first let's prove to ourselves that these are definitely are similar triangles.
På den måde kan vi finde ud af, hvad CF vil være. Lad os først bevise, at de her trekanter er ligedannede.This large round rug in natural jute offers color-coordinated confetti motifs similar triangles, points and lines.
