Solve sides on an isosceles triangle
Test your understanding of solve sides on an isosceles triangle by practicing it! Work through the below exercises to use it in practice.
🎙️
What do we know about the sides on this triangle
🎙️
First let's identify the type of triangle. It has two identical angles, so it's isosceles
🎙️
That means that the two sides touching the unique angle are identical, so 'X' = 15
🎙️
However, without an angle measurement, we don't know anything about 'Y'
