What is the measure of a base angle of an isosceles triangle if the measure of the vertex angle is 42 and two congruent sides each measure 21 units?
The length of the congruent sides makes no difference to the measured angles. Assuming the base angles are the congruent angles, then: angle = (180o - other_angle) ÷ 2 = (180o - 42o) ÷ 2 = 69o
What is the measure of a triangle's third angle if 2 angles are each 42 degree?
96 degrees
What is the measurement of the vertex angle of an isosceles triangle is the measure of one of its base angle is 42?
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.
What is the measure of a base angle of an isosceles triangle if the measure of the vertex angle is 42 and the two congruent sides each measure 21 units?
69 degrees 180-42 = 138 138/2 = 69 degrees You do not need the measure of the side to derive the answer.
