Solve angles on an isosceles triangle
Test your understanding of solve angles on an isosceles triangle by practicing it! Work through the below exercises to use it in practice.
🎙️
What do we know about the angles on this triangle
🎙️
First let's identify the type of triangle. It has two identical sides, so it's isosceles
🎙️
That means that the two angles on either end of the unique side are the same
🎙️
Since the inside angles must add up to 180 degrees, we can subtract and divide by 2
🎙️
So our angles are both 70 degrees
