The base of an isosceles triangle is 3 cm less than the length of the equal sides if the perimeter of the triangle is 36 cm find the length of each sides?

b=l-3
P=2l+b
36=2l+b
Sub b=l-3 into 36=2l+b
36=2l+b
36=2l+(l-3)
36=2l+l-3
39=3l
l=13 cm
Sub l=13 into b=l-3.
b=l-3
b=13-3
b=10 cm
Therefore, the length of each of the two equal sides is 13 cm and the base is qual to 10 cm.

What is a triangle with two sides of equal length?
An isosceles triangle is a triangle that has two sides of equal length.
What is the difference in an equilateral triangle and an isosceles?
All 3 sides of an equilateral triangle are equal in length Only 2 sides of an isosceles triangle are equal in length
What is the length of the sides of an isosceles triangle?
The length of the sides of an isosceles triangle are not set in stone. An isosceles triangle is defined as a triangle with at least two congruent sides. Equilateral triangles; that is, triangles in which all sides are of equal length are also considered to be isosceles triangles. Therefore, as long as at least two sides of the triangle are congruent, (Of equal length) said triangle is an isosceles triangle.
A triangle with 2 sides equal in length?
Isosceles triangle.
What kind of triangle has two sides of equal length -?
It is an isosceles triangle.
What is the difference between a triangle and an isosceles triangle?
An isosceles triangle has to have two sides of equal length. An isosceles triangle has to have two sides of equal length.
How do you find a perimeter of an isosceles triangle?
Assuming that neither of the sides of equal length is the base, Perimeter = Base + 2*Slanted sides.
Does a isosceles triangle have all sides equal?
No, an isosceles triangle has two sides of equal length. An equilateral triangle has all three sides of equal length.
Formula of perimeter of isosceles triangle?
Lengths of: equal side+equal side+base = perimeter
What kind of triangle has at least two sides of equal length?
A triangle with at least two sides of equal length is called an isosceles triangle.
What is an isosceles triangle and a scalene-triangle?
An isosceles triangle is when only two of the triangle's sides are equal in length. A scalene triangle is when no sides are equal in length. There is also an equilateral triangle which all of the triangle's sides are equal.
What is a triangle with two sides of equal length?
An isosceles triangle is a triangle that has two sides of equal length.
What is the difference in an equilateral triangle and an isosceles?
All 3 sides of an equilateral triangle are equal in length Only 2 sides of an isosceles triangle are equal in length
Does an isosceles triangle that the sides are all of different length?
No that triangle is the scalene triangle the isosceles means 2 sides have equal length. :)
What is the length of the sides of an isosceles triangle?
The length of the sides of an isosceles triangle are not set in stone. An isosceles triangle is defined as a triangle with at least two congruent sides. Equilateral triangles; that is, triangles in which all sides are of equal length are also considered to be isosceles triangles. Therefore, as long as at least two sides of the triangle are congruent, (Of equal length) said triangle is an isosceles triangle.
What are the rules for an isosceles triangle?
An isosceles triangle has two sides that are equal in length and thus two equal angles.
How do we determine that the isosceles triangle is an isosceles triangle?
2 interior angles are equal and 2 sides are of equal length.
