That is a RIGHT triangle. You have to know the length of one of the sides to determine the length of the other two. The formula used is A squared plus B squared equals C squared. Imagine a triangle with a vertical line 3 inches long. Call that vertical line "A". Starting at the base of the vertical leg draw a horizontal line to the right that is 4 inches long. Call that horizontal line "B". Now connect the top of "A" to the right end of "B" with a diagonal line. Call that line "C". That diagonal line is 5 inches long. We know this because 3 squared (A) is 9 and 4 squared (B) is 16 and 9+16=25, the square root of which is 5.

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 a triangle with sides of lengths 16 30 and 35 a right triangle?
No because it does not comply with Pythagoras' theorem.
How do you find the sides of a 30 60 and 90 degree triangle?
you cannot determine the sides of a triangle by the angle measures alone because any triangle with different side lengths can have these angle measurements. However if you do know the length of any one of the sides, you can calculate the lengths of the other two sides.The shortest side is the one opposite the 30 degree angle.The hypotenuse (opposite the 90 degree angle) is always twice the length of the shortest side opposite the 30 degree angle.The side opposite the 60 degree angle is always the length of the side opposite the 30 degree angle times the square root of three (about 1.73205).
How many sides a polygon have with an angle 30?
Smallest possible interior angle of regular polygon is 60 degrees (triangle). The greater the number of sides, the greater each interior angle. If exterior angle is 30 degrees, the polygon has 12 sides.
Is a triangle with sides of lengths 20 21 and 30 a right triangle?
No.(20)2 = 400(21)2 = 441(20)2 + (21)2 = 881(30)2 = 900(20)2 + (21)2 is not equal to (30)2
