In the diagram below, BC= QR=2, AC= PRy, and triangle PQR is a right
triangle. Use the drop-down menus to complete the proof that if the equation
2²+y=22 is true of the side lengths in triangle ABC, then triangle ABC must be a
right triangle.
R
Triangle PQR is a right triangle
Click the arrows to choose an answer from each menu.
Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to
determine that Choose....
It is given that a² + y² = 22 in triangle ABC, so
Choose....
This information shows that the triangles are congruent
because their three sides are congruent. Therefore, to show that triangle PQR is a right triangle,
we can use corresponding parts of the congruent triangles to show that
Choose...
