Atriangle has sides that measure 5 cm, 12 cm, and 13 cm. what type of triangle is it? a. equilateral triangle b. acute triangle c. isosceles triangle d. right triangle

D )It is a right triangle.

Step-by-step explanation:

Given : A triangle has sides that measure 5 cm, 12 cm, and 13 cm.

To find : What type of triangle is it.

Solution : We have a triangle with sides

Let side a = 5cm

   Side b = 12 cm

Side c = 13 cm.

We can see square of largest side is equal to the square of sum of two other sides.

Since,  

Plugging the values of a, b, c

             25 + 144 = 169

169 = 169

Hence it follow the Pythagoras theorem

Therefore ,D) it is a right triangle.
