Triangles which have exactly the same angles are similar. If two angles match, the third angle will automatically also match as the angle sum is always 180º. We can find similar triangles when a triangle is cut by a line parallel to the base as in the example below: This is because the apex (top) angle is in both triangle ABC and in triangle ADE.
