Explanation:
The answers to number 1 for each triangle are solved exactly how they are written :).
The number 2s of each triangle are just numbers squared. 15 squared is 225. 18 squared is 324.
Triangle 1 is a right triangle because the angle is a right angle and the triangle can be solved perfectly using the Pythagorean Theorem.
