Question

If a right angled triangle doesn't looks like right angled triangle then how it can b.. I've a triangle of sides 5,12,13cm respectively.. Please help me today is my xam.. Is there any theory behind this? Please let me know

Answer 1

How do I find two sides of a triangle when given one side and Theta?Could I find the two missing side lengths of a right triangle if I only know one side length and one angle?How do you find the height of an equilateral triangle using two sides and one angle?Can we find an angle if we know the sides of a right triangle?Given a right triangle ABC, if angle A is 45 degrees, and side a is 4 m., what is the length of side b? Hint: Angle C is the right angle.Ask New QuestionJoseph Ma, works at The InternetAnswered May 21 2016You can’t.Given that the triangle is a right triangle, we only know for sure two thingsThe length of one sideThat a2+b2=c2a2+b2=c2Knowing trig functions won’t help too much because you aren’t given an angle (that makes sin hard)Here’s the proof on why you can’t:Case 1. You know a (or b)Given side a, you do not know b or c, solving for a,a=c2−b2−−−−−−√a=c2−b2which allows c and b to be many possible things, for example, if a = 3,3=c2−b2−−−−−−√3=c2−b2c and b can be 4 and 5 respectively, 10−−√10 and 11 respectively, \sqrt11sqrt11 and 2–√2respectively, or anything else as long as c2−b2c2−b2 is equal to 9.Case 2. You know cc=a2+b2−−−−−−√c=a2+b2this also allows for a lot of flexibility, for example, is c = 5a and b can be 3 and 4 respectively, 20−−√20 and 5–√5 respectively, 21−−√21 and 4–√4respectively, or anything as long as a2+b2a2+b2 is equal to 25.To those who think that in certain cases you can figure it out by special triangles, that is assuming that all three sides are integers. For example, in a triangle with a hypotenuse of 13, the legs CAN be 5 and 12, but they don’t HAVEto be. They can also be 168−−−√168 and 11, or anything as long as the legs satisfy:c=a2+b2−−−−−−√c=a2+b2.Hope this helps! :D

Answer 2

it cannot be a triangle because the sum of two sides of triangle is greater than the third one.But the sides u have given are not possible for a triangle.
may it help u
