Since an isosceles triangle can be represented by two right triangles back to back, you can utilize the pythagorean theorum to solve this example. Specifically:
18cm/2 = 9cm = 1 leg of right triangle (A)
24cm = hypotenuse of right triangle (C)
A squared + B squared = C squared
Altitude = B = square root of (C squared - A squared) = approximately 19.875
The altitude line is perpendicular to the base and bisects the apex of the isosceles triangle.
Yes - the altitude of an equilateral triangle is perpendicular to the side chosen as the base and bisects that side and the opposite angle. Also, the altitude of an isosceles triangle when measured from the third side (the side that is not equal to the other two sides) is a perpendicular bisector of the base and also bisects the opposite angle.

Find this using the Pythagorean theorem (a=(1/2 * 8) b=the altitude c = 6).
Yes! An isosceles triangle has 2 equal sides and two base angles equal.
In an isosceles triangle, the altitude from the vertex angle to the base bisects the base and is also the median, as it divides the triangle into two congruent right triangles. This altitude is perpendicular to the base, creating two equal segments. Consequently, in an isosceles triangle, the altitude, median, and angle bisector from the vertex angle to the base are all the same line segment.
The altitude line is perpendicular to the base and bisects the apex of the isosceles triangle.
Two sides of an isosceles triangle are equal. The base is the other side.

-- An isosceles triangle has two equal sides. -- An isosceles triangle has two equal angles. -- An isosceles triangle has two equal interior-angle bisectors. -- The bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the triangle's base.
When an isosceles triangle is rotated 360 degrees around its altitude, it forms a three-dimensional figure known as a cone. The altitude acts as the height of the cone, while the base of the triangle becomes the circular base of the cone. The two equal sides of the triangle create the slant height of the cone.
Both have equal sides and equal base angles An isosceles trapezoid is made from an isosceles triangle that's had its top cut off parallel to its base
It is an isosceles triangle
equal
Yes, provided that the base is not one of the 2 equal sides. And it's also the perpendicular bisector of the base.
An isosceles triangle has 2 equal base angles and its height is perpendicular from its apex to the centre of its base
No. It need not be the base angles that are equal, it can be one of the base angles and the top angle (if the triangle is tipped over). Also, the base angle are equal in an equilateral triangle - although an equilateral triangle is a special kind of isosceles triangle.
