Question

How can you prove a triangle is a right triangle?

Select one:
a. Use the distance formula to see if at least two sides are congruent.
b. Use the slope formula to see if any sides are perpendicular.
c. Use the distance formula to see if all three sides are congruent.
d. Use the slope formula to see if any sides are parallel.

Answer 1

To prove a triangle is a right triangle, you can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Step-by-step explanation:

A right triangle can be proven using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. So, to prove a triangle is a right triangle, you can measure the lengths of its sides and check if the equation a² + b² = c² is satisfied, where a and b are the lengths of the two legs and c is the length of the hypotenuse.

Answer 2

the answer is C use the slope formula to see if any sides are perpendicular
