Question

State if the three side lengths form an acute, obtuse or right triangle.
5, 12, 13

Answer 1

right angle triangle

Explanation:

if it is a right angle triangle then if you square the 2 samller numbers and add them together it will give you the largest side squared

this is also known as pythagoras therom the equation is
`a^(2) + b^(2) = c^(2)` a and b are the 2 smaller sides

Answer 2

right triangle

Explanation:

This is because pythagoras theory works:

a² + b² = c², where c is the longest side

5² + 12² = 25 + 144 = 169

√169 = 13 ∴ the triangle is a right triangle.

Hope this helps!
