Let the Isosceles Triangle be ∆ ABC with sides AB = AC = 14', and BC = 17'
Draw a line bIsecting angle BAC. This line will be perpendicular to and bisect BC at point D.
Then ∆ DBA (or ∆ DCA) is a right angled triangle with AB the hypotenuse.
Angle ABD = Angle ABC is one of the two equal angles of the isosceles triangle.
Cos ABD = BD/AB = 8.5/14 = 0.607143, therefore Angle ABC = 52.62°
The third angle of the triangle is 180 - (2 x 52.62) = 180 - 105.24 = 74.76°
The angles are therefore 52.62° , 52.62° and 74.76° .

What is is an isosceles triangle?
An isosceles triangle is any triangle with at least two sides of equal length. Logically, an isosceles triangle also has at least two angles of equal size. An equilateral triangle is a triangle with three equal sides and three equal angles (all of which are 60 degrees). Since it has at least two equal sides then it is therefore also an isosceles triangle. This is no different to the way in which a square is also a rectangle, or a circle is also an ellipse. They are simply special cases of the general case.
Does an isosceles have 2 equal angles if it has 2 equal sides?
An isosceles triangle will have (at least) 2 equal angles if it has (at least) 2 equal side. All three sides and angles can be equal and is a special case of an isosceles triangle calle an equilateral triangle.
What is a isosceles triangle?
