we know that
the triangle ABC and triangle EDF are congruent triangles-----> given problem
therefore
we know that
the distance between two points is equal to
Step
<u>Find the distance AB</u>
substitute in the formula of the distance
Step
<u>Find the distance BC</u>
substitute in the formula of the distance
Step
<u>Find the distance AC</u>
we know that
the triangle ABC is a right triangle
so
Applying the Pythagorean Theorem
substitute the values in the formula
round to the nearest tenth
therefore
<u>the answer is</u>
The length of the hypotenuse is equal to
