<Grid Background="#FF4E7BF5" Width="250" Height="250">
    <Grid.Clip>
        <GeometryGroup>
            <!--This RectangleGeometry will show Grid body-->
            <RectangleGeometry Rect="0,0,250,250"/>

            <!--This PathGeometry will cut RectangleGeometry, cut-off right top-->
            <PathGeometry>
                    <PathGeometry.Figures>
                        <PathFigure StartPoint="230,0">
                            <LineSegment Point="250,0"/>
                            <LineSegment Point="250,20"/>
