Use the sine rule to work out one of the sides.
(a/sina = b/sinb = c/sinc)
Then as it is an isosceles triangle the perpendicular dropped from the apex will (a) bisect the base and (b) form a right angle with the base.
Now you know one side and the hypotenuse of a right-angled triangle and you use Pythagoras (a2 + b2 = c2)
to solve the 'other' side of that, which is the height of the isosceles triangle.

What is the angle that is not congruent to the base angles of an isosceles triangle?
The sum of the internal angles of a triangle is 180 degrees. If you know the size of the angles at the base of an isosceles triangle, the final angle can be found by subtracting the size of the two known angles from 180.
How do you find height of isosceles triangle if you only know the length of equal sides and the base?
i can
What is the measure of the vertex angle of an isosceles triangle if the measure of one of it's base angles is 58?

An isosceler triangle has two equal sides?

What is the formula for the area of an isosceles triangle?
The are of any triangle is calculated by the formula: Area = 1/2 x Base x Height
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
In an isosceles triangle the base angles are?
The base angles of an isosceles triangle are congruent.
An angle not congruent to the base angles of an isosceles triangle?
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
What Angles opposite the legs of an isosceles triangle?
An isosceles triangle has three interior angles whose base angles are equal.
The two angles that include the base of an isosceles triangle?

How do you find the base of an isosceles triangle if you know the angles and the height?
well it seems to me that i don't have a CLUE what your talking about !
What is the same about an isosceles triangle and an isosceles trapezoid?
In an isosceles triangle and an isosceles trapezoid, both base angles are congruent
If the base angles of a triangle are congruent then the triangle is isosceles?
It will be either isosceles or equilateral. It is equilateral if all of the angles are congruent.
How many equl angles has a isosceles?

Definition Base angles of Isosceles triangles?
The base angles of an isosceles triangle are the two angles with the same measure, each formed by the intersection between the base of the triangle and one of the two legs.
