Answer:
disagree
Step-by-step explanation:
If the triangle is right, then the square of the longest side must equal the sum of the squares on the other 2 sides.
longest side = 12 ⇒ 12² = 144
7² + 7² = 49 + 49 = 98
Since 144 ≠ 98 then triangle is not right
Answer:
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.
Square and Rhombus are two.
