1. a triangle has side lengths of 6,8, and 10. is it a right triangle? explain

If a triangle is right angle triangle then,

it will satisfy the Pythagorean theorem.

i,e

As per he statement:

A triangle has side lengths of 6,8, and 10

Square of little sides are:

Sum of these square of little sides we have;

⇒

Square of the longer side:

⇒

so, it satisfy the given condition of right angled triangle

Therefore, a triangle with side length 6, 8 and 10 is a right angle triangle.
