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.]
What else can I help you with?
If two sides of a triangle equal 45 what does the third equal and what kind of triangle is this?
If two sides of a triangle each have length of 45 units, then the triangle is isosceles,and the third side can have any length less than 90 units.
What is the rule for the triangle in length and width?
A triangle has 3 sides. The sum of any two sides must be larger than or equal to the length of the third side, and the difference of any two sides must be less than or equal to the length of the third side.
How is an equilateral triangle an isosceles triangle?
An equilateral triangle, by definition, has three sides of equal length. The definition for an isosceles triangle is that it must have two sides of equal length, the other side being free to have any length. Based on these two definitions, we can say that an equilateral triangle is a special case of the isosceles triangle, namely one where the third side is also equal to the other two sides.
What kind of triangle has two sides with length 15 and one side with length 25?
isoscelesAs regard their sides, triangles may beScaleneIsoscelesEquilateralAnd in regard to their angles, triangles may beAcuteRightObtuseEquiangularA triangle is scalene if all of its three sides are 'different'.If only two of its sides are equal, the triangle is called isosceles.A triangle with all three 'equal' sides is called equilateral.So, a triangle with a length of 15 on two sides and a length of 25 on the third side would be Isosceles, since two of the sides are the same.
What is a defintion of an isosceles triangle?
Literally speaking, an isosceles triangle is one which has two sides of equal length. Generally speaking, the third side should be of a different length. [If the third side is also the same length then the triangle would be equilateral, but that may be considered a special case of an isosceles triangel.] Equality of two sides implies that the two angles at the ends of the third side are of equal measure. This may be used as a working definition of an isosceles triangle.
If two sides of a triangle equal 45 what does the third equal and what kind of triangle is this?
If two sides of a triangle each have length of 45 units, then the triangle is isosceles,and the third side can have any length less than 90 units.
The congruent sides of an isosceles triangle?
The congruent sides of an isosceles triangle are the two sides that are equal in length. These two sides are opposite the equal angles of the triangle. The third side, called the base, is not equal in length to the other two sides.
What is the third side an isosceles triangle?
An isosceles triangle has 3 sides 2 of which are equal in length
What is the rule for the triangle in length and width?
A triangle has 3 sides. The sum of any two sides must be larger than or equal to the length of the third side, and the difference of any two sides must be less than or equal to the length of the third side.
What type of triangle has only two sides with equal measures?
An isosceles triangle has two sides with equal measures. The third side can be any length.
What are the measures of all angles in a triangle if 2 sides equal the third side?
If two sides of a triangle are equal in length to the third side, then the triangle is equilateral, and all angles are 60 degrees.
In an isosceles triangle do all sides have equal length?
Oh honey, bless your heart for asking. In an isosceles triangle, only two sides are equal in length, not all three. It's like having two besties who always have your back, while the third side is just there for the ride. So, nope, not all sides are equal in an isosceles triangle, but hey, close but no cigar!

Can the sum of two sides of a triangle be equal to the third side?
no it can not be eaual but it can be greater than The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
Is equilateral triangle always an isosceles triangle?
If an isosceles triangle is defined as one which has two sides (or angles) equal, then YES. But if an isosceles triangle is defined as one which has two sides (or angles) equal, and the third side (angle) different, then NO.
