Question

in an isosceles triangle the base angle are equal and the vertex is 80 degree find the measurement of the base angle​

Answer 1

Answer:

50 each base angle

Base Angle_1 + Base Angle_2 + Vertex = 180

50 + 50 + 80 = 180

180 = 180

Step-by-step explanation:

Sum of interior angles of Triangle is 18- degrees.

2b + vertex = 180

2b + 80 = 180

2b + 80 -80 = 180 - 80

2b = 100

b = 50
