Dallan's law 

Dallan's law is an epigram that is typically stated as: "If angle looks like 90 degrees, then it is 90 degrees."

The law is often followed by mistake in math where someone assumes that an angle in a triangle is 90 degrees so they can use rules that only can be applied to right triangles.

"90 degrees" can sometimes be a metaphor for something else e.g., "If someone sees a car as red, then it is red". This means that a thing can be perceived as something else even though it is obvious that it only can be one thing. A washing machine can therefore be perceived as a rocket launcher if that person is stupid enough.
Example 1:

David: Why do I get the wrong answer when I use the Pythagorean theorem?

Teacher: Beacause it does not contain a right triangle. You probably utilized Dallan's law.

Example 2:

David: What a nice avocado you got there!

Åsa: Thanks David, but that's a potato. I guess you're right though according to Dallan's law.

Kristian Dallapalma is described as a 'rat' where ever he goes, sadly this is due to his disfigured body. Many things such as his torso, legs, and head are all out of shape leading to a staggering height of 4 foot 2. Nothing can fix this.

Dalana is a wonderful beautiful girl. She is a really loud person but fun to be around she is a really good friend and a keeper if you get her as a girlfriend. She is good with kids and will be a great mom some day in the future. Dalana is not to confident in her body but has a beautiful body most girls would kill for. She is good at most sports but that don’t mean that she does them. She is a smart girl but acts dumb. She has many friends because she is a amazing person. Dalana is a very sweet girl who try’s to be friends with everyone and hates to see people sad, but can have attitude like no one else and bitchy when needed. She don’t let people talk down to her or her family, nor friends. Sad thing about dalana boys don’t see her for what she is so she don’t have many boyfriends but will one day find the right one. She is a caring person and overall a wonderful person is you have a dalana in your life don’t let her go.
