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?

One

Step-by-step explanation:

We know that two triangles are congruent if they have the same size and shape. This can be thought as "if two triangles are congruent, then one of the triangles is a reflection or a rotation of the other, this means that there is only one unique triangle but in two different forms"

One of the criteria to see if two triangles are congruent is the SSS (Side-Side-Side) criteria.

This means that if two triangles have the same length in their 3 sides, then the triangles are congruent.

This implies that all the triangles that with sides measured A, B and C (where A, B and C can be any number) are congruent between them.

This means that with the sidelengths A, B and C, we can draw only one unique triangle.

Particularly for the case of Kaleem, she haves the sidelengths:

5cm, 8cm, and 7cm

And as we said before, this set of sides can draw only one unique triangle.
