You can put this solution on YOUR website! What other measurements do you have?
Vertical angle?
Length of sides?
Height?
Area?
In all triangles the measures of the angles add up to : .
In isosceles triangles in particular, the base angles have the same measure:
IF you have VERTICAL ANGLE , -->-->--> .
Otherwise, there are other equations that relate other measurements
(you would probably need 2) to the measure of the base angles.
