Yes, we can.

Explanation:

To construct a triangle, given three sides, we must have the size of the largest side less than the sum of the other two sides.

Here, the largest side is 1515 and 15< 15+115<15+1, hence, we can draw the triangle.

To draw the triangle just draw an arc of a circle with radius 1515 cmcm and then choosing a point on the arc draw another arc of 11 cmcm radius to form a chord of length 11 cmcm on the circle of radius 1515. Now, just join the ends of the chord to center of the circle with radius 1515 cmcm and you have the triangle.
