What is the base length of an isosceles triangle that two sides are 34 cm and the height is 30?
Draw a line joining the top vertex to the middle of the base.
This divides the triangle into two right-angled triangles, which are congruent (both have the same side lengths and angles).
Each right-angled triangle has a hypotenuse length of 34 cm (the hypotenuse is the side opposite the right angle). They also have a side which is the height of the triangle, 30 cm.
By Pythagoras' theorem, the third side of each right-angled triangle is 16 cm long
because 342 - 302 = 1156 - 900 = 256 = 162
The base of the isosceles triangle is twice that, so it's 32 cm long.

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.
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. :)
How are isosceles triangle and a scalene triangle are different?
An isosceles triangle has two sides that are the same length. A scalene triangle does not have any sides that are the same length.
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 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.
How do you find height of isosceles triangle if you only know the length of equal sides and the base?

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.

Are all sides congruent in an isosceles triangle?
No. An isosceles triangle has only two sides of equal length.
What does an isosceles triangle have?
An isosceles triangle has two congruent sides, i.e., two sides that are of equal length.
How do you find the height of an isosceles triangle when given only the three side lengths?
Make it a right triangle where one side of the right triangle is half the length of the non-identical side of the isosceles, the hypotenuse of the right triangle is the length of one of the identical sides of the isosceles triangle, then use the Pythagorean theorem. a^2+b^2=c^2. Where "a" is the length of one of the identical sides, and "c" is the length of half the non-identical sides. Solve for "b" and that is your height.
