# Finding angle of a reflected isosceles triangle

Brown Arrow

## Homework Statement

I am trying to find the following (marked in red) angle, I know that the radii to the points of contact make an angle θ with the horizontal.

## Homework Equations

all angles of a triangle add up to 180 degrees.
isosceles triangle, has two equivalent sides

## The Attempt at a Solution

I tried using symmetry and found the part in red is $\pi$ - 2$\theta$
but according to the text, the angle is 2$\theta$. I am confused on why is is 2$\theta$
