In an isosceles triangle there are two equal sides and two equal angles. In a triangle ABC, if angle A is between the sides of equal length, then angles B and C are equal.Without knowing which angle (A, B or C above) is 66o there are two possible answers:If the 66o angle is between the two sides of equal length (angle A) then the other two angles (B and C) are (180o - 66o) / 2 = 57o each.If the 66o angle is not between the sides of equal length (angle B or C), then the other two angles are 66o (the other angle of C and B) and (angle A) 180o - 66o x 2 = 48o.

If it's a right angle triangle then:- a2+b2 = c2 where 'c' is the hypotenuse and the square root of this is the length of the hypotenuse when 'a' and 'b' are the other sides of the right angle triangle.

Like a 3 sided triangle each side being of equal length -- correction -- That's a 60 degree angle!. A 45 degree angle is formed in a right-angle triangle when the other two sides are of equal length. --correction-- learn your maths!?! .....................that was mean sorry

This is the description of the Pythagorean theorem. It applies to any "right" triangle -- that is, a triangle with one angle of exactly 90-degrees, and two other angles that add up to 90-degrees. A = the measurement of the length of one side of the triangle making up the 90-degree angle. B = the measurement of the length of the OTHER side of the triangle making up the 90-degree angle, perpendicular to "A". C = the measurement of the length of the third side of the triangle opposite to the 90-degree angle, also called the hypotenuse In any right triangle, A-squared + B-squared = C-squared

A hypotenuse is the longest side of a right angled triangle. The length of a hypotenuse can be found using the Pythagorean Theorem. This states that in a right angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. This means that to find the length of the hypotenuse, you need to know the lengths of the other two sides.

-- Like every triangle, a right triangle has three interior angles.-- Unlike any other triangle, one of the angles in a right triangle is a right angle.The other two are both acute angles.-- One acute angle is the angle whose cosine is length of one leg / length of hypotenuse-- Other acute angle is the angle whose sine is length of the same leg / length of the hypotenuse-- The length of the hypotenuse is the square root of [ (length of one leg)2 + length of other leg)2 ]

In a right triangle, the tangent of an angle other than the right angle is the ratio of the length of the side opposite the angle over the length of the side adjacent to the angle (the side between the angle and the right angle).

In an isosceles triangle there are two equal sides and two equal angles. In a triangle ABC, if angle A is between the sides of equal length, then angles B and C are equal.Without knowing which angle (A, B or C above) is 66o there are two possible answers:If the 66o angle is between the two sides of equal length (angle A) then the other two angles (B and C) are (180o - 66o) / 2 = 57o each.If the 66o angle is not between the sides of equal length (angle B or C), then the other two angles are 66o (the other angle of C and B) and (angle A) 180o - 66o x 2 = 48o.

I don't think it is possible. You would have to know at least one other measurement such as the angle between the length and width or the length of one of the sides.

The answer may refer to a triangle for which the length of two sides and the measure of an angle - other than the included angle - are known.

The Pythagorean Theorem explains (or permits calculation of) the length of one side of a right triangle if the lengths of the other two sides are known. A right triangle is a triangle in which one of the three angles is a right angle (i.e. it has 90 degrees) For that kind of triangle, if A = the length of one of the sides making the right angle, B = the length of the other side making the right triangle, and C = the length of the side opposite to the right angle (also called the hypotenuse, then C2 = A2 + B2

All you can say is that the length of the third side will be positive and less than double the length of either of the equal sides. You need to know at least one angle. If that angle is less than 90 degrees (unless it is 60 degrees), you need to know whether it is the angle between the two equal sides or between one of them and the third. [If the angle is 60 degrees then the triangle is equilateral and the third side is the same as the other two.]

An isosceles triangle is a triangle with two equal sides and two equal angles. The two equal sides are called the legs, and the angle between them is called the vertex angle. The two other angles in an isosceles triangle are equal and are called the base angles.

If you have the length of two of the sides and one other angle you can use the law of sines.

If it's a right angle triangle then:- a2+b2 = c2 where 'c' is the hypotenuse and the square root of this is the length of the hypotenuse when 'a' and 'b' are the other sides of the right angle triangle.
