The base of an isosceles triangle is 18 cm long the equal side are each 24 cm long What is the altitude?
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

How you can draw a altitude with isosceles triangle?
The altitude line is perpendicular to the base and bisects the apex of the isosceles triangle.
Can an altitude be a perpendicular bisector?
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.
How do you find height of isosceles triangle if you only know the length of equal sides and the base?

If an isosceles triangle has a leg of 6 and a base of 8 what is the altitude?
Find this using the Pythagorean theorem (a=(1/2 * 8) b=the altitude c = 6).
An isosceler triangle has two equal sides?
Yes! An isosceles triangle has 2 equal sides and two base angles equal.
In an isosceles triangle what are the altitude and media?
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.
How you can draw a altitude with isosceles triangle?
The altitude line is perpendicular to the base and bisects the apex of the isosceles triangle.
Which is the base of an isosceles triangle?
Two sides of an isosceles triangle are equal. The base is the other side.
Does the altitude to the base of an isosceles triangle bisect the vertex angle?

What are 2 properties of an isosceles triangle?
-- 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.
What three dimensional figure is formed by rotating an isosceles triangle 360 around its altitude?
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.
How an isosceles trapezoid is related to an isosceles triangle?
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
What is it called if base angles are equal in a triangle?
It is an isosceles triangle
The base angles of an isosceles triangle are?
equal
Is the altitude of an isosceles triangle the angle bisector of the vertex?
Yes, provided that the base is not one of the 2 equal sides. And it's also the perpendicular bisector of the base.
How do you find the base and height of an isosceles triangle?
An isosceles triangle has 2 equal base angles and its height is perpendicular from its apex to the centre of its base
Is it only in an isosceles triangle that the base angles are equal?
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.
