If that '56' has units of 'degrees', then the vertex angle is 68 degrees.
If it is an isosceles triangle then the base angles must be equal angles of 69 degrees because there are 180 degrees in a triangle and 42+69+69 = 180 degrees
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°
an isosceles triangle can have any vertex angle less than 180 and greater than 0, as long the other two angles are equal. an isosceles triangle with a vertex of 179 degrees would just have the other two angles be 0.5 degrees. A right triangle with matching angles (both 45 degrees) would be both a right triangle and isosceles triangle.
104 degrees: 180 - (2 x 38)
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
If that '56' has units of 'degrees', then the vertex angle is 68 degrees.
80 degrees
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
If your "53" is in degrees, then the vertex angle is 74 degrees.
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
