Kaleem wanted to draw a triangle where the sides measured 5 cm, 8 cm, and 7 cm. How many unique triangles could Khaleem draw that fit these dimensions?

The three side lengths determine a triangle up to its shape and size, as long as they satisfy the triangle inequality. Here, 5 + 7 > 8, 5 + 8 > 7, and 7 + 8 > 5, so a triangle can be formed. Any triangle with sides 5 cm, 8 cm, and 7 cm is congruent to it, so only 1 unique triangle can be drawn.
