What is the perimeter of ∆ ABC?

To find the perimeter of \triangle ABC we use the Pythagorean Theorem which tells us that |AB|^2 = |AC|^2 + |BC|^2. Since |AC| = 5 and |BC| = 12 we find that |AB| = \sqrt{169} = 13. The perimeter of \triangle ABC is then 5 + 12 + 13 = 30 units.

Does a triangle have a perimeter?

The perimeter of a triangle is simply the sum of its three sides.

What is the perimeter of a triangle in centimeters?

Perimeter Of Triangle. Always include units in the final answer. If the sides of the triangle are measured in centimetres then finals answer should also be in centimeters. In this example, The sides of the length are each 10 cm, so the correct value for Perimeter is 30 cm.

What is the missing side length of a triangle whose perimeter?

Solution: Since all three sides are equal in length, the triangle is an equilateral triangle. Example 3: What is the missing side length of a triangle whose perimeter is 40 cm and two sides are 10 cm each? Length of two sides is the same i.e. 10 cm. Thus, the triangle is an isosceles triangle. Missing side length is 20 cm.
