How do you solve a 45 45 90 triangle?

If its angles are 45, 45 and 90 degrees then it is an isosceles right angle triangle and its properties can be worked out using Pythagoras' theorem and trigonometry


How do you find the hypotenuse of 45 45 90 right triangle?

Using Pythagoras' theorem


How to figure the length of one side of a triangle with only the length of the long side and some degrees?

you might be able to use tangent, sine, or cosine. you might be able to use the Pythagorean theorem, or you can used 30-60-90 triangle theorem or 45-45-90 triangle theorem


If you have a 45-45-90 triangle with a hypotenuse of 16 root 2 how do you find the other sides?

The other sides are both 16. This is because in a 45-45-90 triangle the legs are congruent because of the isosceles triangle theorem, and also the hypotenuse of the triangle is equal to the leg times root 2. That is because of the 45-45-90 triangle theorem. So in a summary the legs are congruent and the hypotenuse is equal to the leg times root 2.


A 45 45 90 triangle has a hypotenuse of length 7 What is the length of one of its legs?

What is the about statement about a 45-45-90 triangle?

A triangle with a 90 and two 45 degree angles is an isosceles right angle triangle.


Can an isosceles triangle Always be a right triangle?

In an isosceles triangle, two angles, and therefore sides (Base Angle Theorem), are congruent. This does not mean that all isosceles triangles are also right triangles - there is only one (45, 45, 90 triangle).


What is a triangle that has angles that measures 45 45 90 degrees?

It is an isosceles triangle. 45 + 45 + 90 = 180 degrees


Is an isosceles right triangle always a 45 45 90 triangle?

Yes.


Is a triangle with two congruent angles always a 45-45-90 triangle?

No because an isosceles triangle has various two congruent angles. A 45-45-90 triangle is technically an isosceles triangle.


If the hypotenuse in a 45 45 90 degree triangle is 20 then what is each leg?

Use Pythagoras' theorem: Each leg is about 14.14213562 units in length.


A 45 degree-45 degree-90 degree triangle has a hypotenuse of length 11 what is the length of one of its legs?

7.778174593 units, solved with the help of Pythagoras' theorem.


A triangle that has 45 45 90 degrees is a n?

Left triangle.


What is the 45 45 90 triangle?

It is a right angled isosceles triangle.


In any 45-45-90 triangle the length of the hypotenuse is times the length of a leg.?

False because in any right angle triangle Pythagoras' theorem states that a^2 +b^2 = c^2 whereas 'a' and 'b' being the legs of the triangle with 'c' as its hypotenuse


If two angles of a triangle each measure 45 degrees what is the third angle?

If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.


How can you find the measures of the sides of a triangle?

There are many theories and formulas that can be applied to find the length of each of the sides of a triangle. The most common is the Pythagorean Theorem: a2+b2= c2 . The letters: "a , c" are the two legs. The hypotenuse is the letter "c". For a 30-60-90 triangle you can use a special formula, as well as a 45-45-90 triangle.

Is an isosceles triangle similar to a right triangle?

It can be similar to each other with the base angles theorem. It would be 90 degrees and on the bottom would be both 45 degrees and if you would turn it sideways, there is your right triangle.
