Sign In
Calculate the distance between the given points and use the Converse of the Pythagorean Theorem.
No.
To determine whether the given points form a right triangle, we will start by plotting and labeling the points. Then, we will connect them on a coordinate plane.
Now that we can see the triangle, we will need to measure the side lengths and then use the Converse of the Pythagorean Theorem to check whether the lengths create a right triangle.
Substitute values
Calculate power
Add terms
sqrt(LHS)=sqrt(RHS)
Rearrange equation
With these values, we can calculate the distances.
Distance | Pythagorean Theorem | Solve |
---|---|---|
Between B and C | 9^2+ 4^2=( d_(BC))^2 | d_(BC)= sqrt(97) |
Between C and A | 11^2+ 2^2=( d_(CA))^2 | d_(CA)= sqrt(125) |
Finally, let's recall the Converse of the Pythagorean Theorem.
