Amir and Quader rode their scooter a distance of 50 meters to Teen Summit. Amir rode his scooter at a rate of 2 meters every second. Quader started 10 meters ahead and rode 3 meters every 2 seconds.

Step-by-step explanation:

Triangle PQR is given to be a right triangle, so the Pythagorean Theorem can be used to determine that PQ is the hypotenuse.

It is given that x^2 + y^2 =z^2 in triangle ABC, so AB = PQ.

The information shows that the triangles are congruent because their three sides are congruent. Therefore, to show that triangle ABC is a right triangle, we can use corresponding parts of the congruent triangles to show that BCA is a right angle.
