Question 1013076: Triangle ABC is isosceles with vertex A. The ratio of A:B is 2:4. What are the measures of the three angles of the triangle? Answer by macston(5194) (Show Source):

Ratio A:B is 2:4 is 1:2
.
A+B+C=180
.
If A=C, B=2A:
A+2A+A=180
4A=180
A=45
B=2A=2(45)=90
C=A=45
.
If B=C, B=C=2A
A+2A+2A=180
5A=180
A=36
B=2A=2(36)=72
C=2A=2(36)=72
