What is the mechanical advantage of an isosceles triangle with the hypotnuse as 12.65ft and two legs of 12ft and 4ft?
That's not actually an isosceles triangle. Isosceles triangles have two sides that are the same. However in general triangles are strong when used in the construction because they form naturally rigid shapes, which doesn't allow distortion of the angle.
How do you do pythagorean theorem?
The Pythgoren Theorem is a2 + b2 = c2. It is used for right triangles. The "c" is the length of the hypoteneuse, and "a" and "b" are the lengths of the two legs of the triangle. You use it by plugging in 2 dimensions that you know to find the third that you do not know.
How do you find the legs of a triangle?
Triangles don't have legs, legs implies the triangle's corners are perpendicular to a surface, this chnages the shape of the triangle into a origami shaped object like a small table, which can't exsist fully in 2D.
How do you find both legs of a triangle with only the hypotenuse?
You can't. The hypotenuse alone isn't enough to tell you anything about the lengths of the legs. There are an infinite number of different right triangles that all have the same hypotenuse but different legs.
The LL theorem states that for right triangles two congruent what are sufficient to prove congruence of the triangles?
LEGS
The area of right triangles with legs 2 and 2?
the answer is 4
Are the sides of right triangles also called legs?
yes they are!
Are some right triangles are also equilateral triangles?
No because all right triangles have 2 legs and a hypotenuse. The hypotenuse is always longer than either leg so right triangles can't be equilateral triangles.
Two right triangles are congruent if the legs of one triangle are congruent to the legs of the other triangle?
true
Why are the gateway arch's legs triangles?
Because that's how the architect designed them.
How do you find an angle of a right angled triangle if you know 2 sides?
You use the Pythagorean theorem, which can only be applied to right triangles: a2+b2=c2, where a and b are the triangle's legs and c is the triangle's hypotenuse. Plug the two sides you know into the equation, then solve for the unknown side.
To use the HL Theorem to prove two triangles are congruent the triangles must be right triangles. Which other conditions must also be met?
The two legs must be corresponding sides.
