Answer:
Inscribed word means to draw something inside something.
But In geometry it means drawing one figure inside another figure so that it just touches.
When a circle is inscribed in a polygon then it means side of polygon is tangent to circle or sides and circle touches at one point.
While a polygon is inscribed in a circle then it means its vertices touches the circle or its vertices are on circle.
So, A Triangle is inscribed in another figure if each vertex of triangle touches that figure.
Therefore, It is TRUE.
