Thethree sides of a triangle measure 810 and 12 units is this a right angle?

The given triangle is NOT A RIGHT ANGLED TRIANGLE.

Step-by-step explanation:

Here, the three given sides of the triangle are:

8 units, 10 units and 12 units

Now, for any triangle to be a right angle:

by the PYTHAGORAS THEOREM:

The longest of all sides id the hypotenuse.

⇒ H  = 12 units

Let us assume, B = 8 units, P = 10 units

Now, here checking the condition:

Hence, the given triangle is NOT A RIGHT ANGLED TRIANGLE.

after simplifying it i got: -36.25 as my answer. hope that !

just needed some points but try socratic
