The lengths of 2 sides of an isosceles triangle are 7 and 5 what are all the possible lengths of the third side?
An isosceles triangle must have two sides of equal size.Since you have a side of 7 and 5, for it to be isosceles, your third side must be either 7 or 5.
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.
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 relationships exist between the two congruent sides of an isosceles triangle and its base?
The angles where the equal sides meet the third side of the triangle are equal angles.
Which is the base of an isosceles triangle?
Two sides of an isosceles triangle are equal. The base is the other side.
What is the third side an isosceles triangle?
An isosceles triangle has 3 sides 2 of which are equal in length
What triangle has two equal sides and one longer one?
An isosceles triangle. It is an isosceles triangle even if the third side is shorter.
The lengths of 2 sides of an isosceles triangle are 7 and 5 what are all the possible lengths of the third side?
An isosceles triangle must have two sides of equal size.Since you have a side of 7 and 5, for it to be isosceles, your third side must be either 7 or 5.
How many congruent sides does a isosceles triangle have?
An isosceles triangle has two congruent sides.
What is a triangle that has two sides the same and the therid different?
It is an isosceles triangle that has two equal sides and the third side being different
Is a isosceles acute triangle a regular polygon?
A regular polygon is one which has all equal sides. But in an isosceles triangle, only 2 sides are equal. The third side has a different measure.Thus an isosceles acute triangle is not a regular polygon.
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 a defintion of an isosceles triangle?

This may be used as a working definition of an isosceles triangle.
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.
If a triangle has two sides that are 15 inches each and the third side measures 10 inches what kind of triangle is it?
This would be an isosceles triangle.
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.
