Answer:
Isosceles triangle.
Step-by-step explanation:
A triangle has been given in this question with the sides 5 cm, 5 cm, 7 cm.
As per definition of the triangle if two sides are equal then opposite angles of these corresponding sides will be equal.
More than this if two sides of a triangle are equal then the triangle is called as isosceles triangle.
Therefore the given triangle with the equal sides 5 cm, 5 cm will be the isosceles triangle.
