70
What is the measure of the vertex angle of an isosceles triangle if the measure of one of it's base angles is 56?
If that '56' has units of 'degrees', then the vertex angle is 68 degrees.
If the vertex of an isosceles triangle has a measure of 70 what is the measure of one base angle?
If the vertex of an isosceles triangle has a measure of 70° what is the measure of one base angleANSWER:Isosceles = 2 legs, 1 vertex, 1 baseTriangle = 180°if its vertex measure 70° , 1 leg ____? + 1 leg____? =180° and all isosceles triangle has congruent legs.180°- 70°=110° then 110° divided by 2 =55°=vertex of an isosceles triangle measure 70° and its 2 legs measure 55°
If a base of an isosceles triangle is 75 degrees What is the measure of the vertex angle?
30o
What is the measure of the vertex angle of an isosceles triangle if one of its base angle measure 54?
Since you know one base angle is 54 then the other base angle is also 54 making a total of 108. Since a triangle is 180, your vertex angle is 72.
